Upgrade route from AMD X6 1090T and 790FX board (with CF GPUs)

post #1 of 17
Thread Starter 
Hi guys, like the thread title says, I'd like some input on a possible upgrade route from my current CPU, a Phenom II X6 1090T running at around 4.0 GHz. It's mostly about games, as I''m not seeing the FPS I'd like to see in CPU-demanding games - I figure it's not a lack of graphics processing power that is to blame for that, as I'm also using dual 6950 2GB cards (@900MHz) in Crossfire. Gaming res is 2560x1440 though. Unfortunately, my board (Gigabyte MA-790FXT-UD5P) doesn't seem to allow the upgrade to FX8350, otherwise I'd probably go for that and be done with most of my requirements for about €150 - any information to the contrary would of course be very appreciated. Those requirements are as follows (in that order):

- good improvement over the Phenom II in CPU power, for games such as FSX, Mount & Blade Warband and Planetside 2
- GPU (=Crossfire) performance shall not take a hit (I'm fearing that going from 16x/16x on the 790FX board to a 8x/8x PCIe might do that)
- Price for the upgrade less than 300 Euros in total (since prices may vary between US and Euro markets, let's just say I want to keep it in the "reasonable" category, so no 3770k and/or high-end boards at retail price for me smile.gif ).
- SATA 3 support for my Crucial M4 SSD
- Cooling medium is water, overclocking goals are moderate (whatever one can achieve with about +0.1V overvoltage).
- optional: capability for triple CF

I'm right now thinking along the lines of a Sandy CPU (2600k?) with a mid-level Z77 board, all of which seem to be limited to 8x/8x CF; but I'd love to hear some of your input, especially some out of the box thinking such as used socket 1366 i7 (Xeon?) CPU and a board with a ****load of PCIe16x slots in combination with a decent aftermarket SATA3 controller maybe, if such a thing exists... I'm very willing to take a risk and buy used stuff from ebay or do something unconventional - I just don't like the idea of paying through my nose for a 16x/16x Z77 just to score even with my trusty old 790FX from two years ago.

So thanks for your input,

Chris

X8x8 will not limit your gpus, no effect actually on gaming. So go with your idea of a 2600k and mid range z77 mobo.

^this. i agree because of fsx. sadly that runs best with intel based system. mind you that even with the i7 you will get bad fps with PS2.

if you can wait and save up for either steamroller or haswell would be another route along with one highend gpu.

btw, that thuban is still fetching quite a good amount.

Alright, I guess you're right, I either should be out hunting for 2600k's or waiting for the next gen CPU - but something like this X58 board is just soooo tempting. I mean, six DDR3 slots and four proper PCIe slots (at somewhat unusable spacing, but still)... If only there was a way to get decent SATA3 in that thing, I'd be all over it - I mean, the upper end 1366 i7's should still be capable enough for my demands, right?

decnet, the 2600K is already old . . . the x58 . . . well. unless you are getting the six-core i7, it would be almost a sidegrade. stay with the sandy or wait. don't think much of the x8/x8 with the 6950s.

Well, ok ok... i'll try to stay focussed on modern hardware. But to say the 2600k is old in terms of performance is a bit over an overstatement I suppose - it performs about as good or even better than the 3570k that replaces it, at least in all the current tomshardware.com CPU tests I could be bothered to have a look at (total computing time, 3dMark, Crysis 2) - are THG known to be intel-biased in any way? serious question! The new Ivy's/Sandy-E's are just more energy efficient, that's all I can gather from there. In the same tests, the top-of-the-line 1366s (970 and up) also seem to be hanging in there quite far up, still on eye level with the best modern CPUs in terms of performance, it's just that they eat up a lot more energy and are in fact , like you guys have pointed out, still rather expensive for what are by now ~4 year old CPUs, which is in fact the best reason to stay away from them, even if the boards are quite temptingly well-featured and affordable by now. So let's keep it at this promise: Unless I come across an i7 980X at €150 or some similarly unrefutable offer, I'll go the 2600k/Z77 route smile.gif

Thanks for your advice, you guys!

Alright, now I really got it - I'll create a Z77 system using an older GPU and the cheapest 1155 CPU (Pentium G860 or i3 2120 or something like that) I can get my hands on for now. This will serve as a mini-LAN-party tool (a few of my friends have no gaming computer, so if I want to play anything other than their annoying console games with them, I might as well build them a system) as well as a backup PC until Haswell arrives. I figure that a number of people - those who are not content with being second best - might end up dumping their Sandy/Ivy i7 CPUs on ebay when there is a new king in town, so I'll be watching out on that front and try to score me a bargain. When I finally score that CPU, I'll switch boards, sell the cheap CPU, and live happily ever after -until next year or so that is, obviously smile.gif.

my 2cents.gif. 3770K>2700K/2600K>3570K.

here are some benches you can compare to your sig. GPU at stock and CPU at 4.5GHz.

I used Adrenalin on this . . .



this is actual game play . . .

Hey, that looks really promising - I'm scoring about 3000 points less on 3dmark 2011 physics, and in Planetside 2 my fps are often dropping below 25fps in big sieges and similar mass-trigger-happy situations. Nice OC on that 7950 btw, that is not air-cooled, right? I mean, I've heard that the 7000 series takes overclocking quite nicely, but 800->1200... that's a bit more than that smile.gif.

Frankly, I believe there is an underlying issue here that you aren't seeing. Your overclock being bad, causing a performance hit, temps out of line, a bad Crossfire profile, Bios related issues...etc.

I have built about half a dozen rigs with the Phenom II line and with cards ranging from the 6850 up to 7950 on the AMD side, and several with Nvidia 400, and 500 series cards. I have yet to see a situation of the CPU's choking out while gaming. These games include; BF3, BFBC2, WoW, Guild Wars, League of Legends, Modern Warfare....so on and so on.

My point?

Before you start throwing money around, I would really dig down and look for other causes. First, start by pulling one of your cards out, playing, seeing what happens. If it looks good, take out that card, put the other card in, play. Still having the problem? Dump your Bios to default, write down your overclock settings. Problem still happening after this? Without the OC test the cards again, in the same fashion as previously mentioned. Still having the problem? Update the Bios on the cards, and lastly update the Bios on the motherboard.

Another option, outside of gaming with the individual cards would be to run OCCT, http://www.ocbase.com/, on each card. If you have faulty VRAM on one of them, you are going to take it in the pants on performance.
