I have a dilemma!

post #1 of 5
Thread Starter 
Ok, so here's the deal:

I have a Asus p5q pro turbo that I purchased recently and would like to upgrade, but I need a cost-effective solution.

I also have an evga gtx 470 with a decent overclock (for what it is) and an EK WB.

My motherboard is Crossfire only (ATI).

Here's my question:

Should I:
(A) Sell the GTX470 and WB and pick up 2 ATI and 2 WBs (I was thinking 5870s or something equivalent to 2x GTX 470s)
(B) Keep the GTX470 + WB, buy another GTX470 + WB, and a new mobo (that supports LGA775, DDR2, and SLI)
or
(C) Keep what I have and just wait to upgrade later down the road (I7 SB, DDR3, SLI/Crossfire compatible)

Thanks for your time. My specs are listed in my sig. If you are interested in voltages as well let me know (I think I won the lottery)

Here's one way of seeing it:
1.It's a good idea, albeit maybe a bit too difficult to actually achieve. You may loose money while selling/buying other parts. See2)
2.Or you could just get another GTX 470 and use the SLI hack in order to use SLI on your board. There were just too many folks having issues with 980 SLI motherboards (sk 775 w/ SLI). If the SLI hack isn't an option, then better 1) or 3)
3.At some point you are going to upgrade anyway. However since you aren't convinced you should upgrade, then maybe you shouldn't. Early next year there's Ivy Bridge (22nm SB) and if the Nehalem=>Gulfton is an indication, then IB could be faster while cooler. Food for thought.

After reading this I found out 2 things(oh and +rep'd).

1. I was not aware the SLI hack actually worked. I had heard rumor, but I never looked into it. Do you have any links to a relatively current SLI hack update?
2. 2x GTX470s would be prime because I know how to overclock them relatively well and my case is rather hard to work with due to all the small mods I have (taking out my mobo would be a pain). Buying another GTX470 with WB seems to be my best option assuming that the SLI hack works, and then in a year or a year and a half I can upgrade the whole system as supposed to one component at a time.

p.s. Do you know if a different brand GTX470 and a different WB would work well in SLI? or would I have to match cards and maybe match WBs?

Thanks dragosmp,
ali

EDIT:
Question. Could my 620w PSU handle 2 cards even? Can it even handle what I have currently? Is there anyway to find out?

Thanks, here's a link to OCN's SLI-on-any-motherboard guide:
http://www.overclock.net/nvidia/6708...rd-gtx5xx.html

You can pair different GTX 470s in SLI, but I think there could be some quirks if they aren't clocked at the same frequency. They may both run at the lowest speed of the two, but you can OC the "slower" one to compensate.

Abut the 620W, I replied a few hours ago on another thread, but can't find it. The OP asked if he can use 2x470 SLI & an i7-like Xeon on a 600W PSU - someone provided a link from an anandtech review claiming this setup would take ~570W at the plug, which translates to under 500W consumption of the rig - at stock. So it would work in your case too, but if you OC you'd have only ~100W of headroom before the PSU is overloaded. If you'd OC without Vmod-ing you may have enough headroom.

I was actually reading your blog about that, and I also read the post on the 2x470gtx thread. I don't V-mod, because i hit the lottery with the stuff I have. (1.21v for my proc @ 3.45ghz and 1.06 for my gtx470 OCCT for 10 hrs.) So I think I should be fine for now right? My watercooling stuff doesn't take up too much voltage either I don't think. Maybe i'll grab a bigger PSU too. It shouldn't be too expensive to get an 850w 80+ gold nowadays.
