What do you mean by IQ? Someone suggested that I grab the card and then wait for Haswell in the future. Would this be a wise choice?

Turning the Image Quality up (AA, AF, SSAO/HBAO, DoF, etc) will put more load on the GPU and hopefully cause it to be the limiting factor rather than the CPU. Basically if your GPU isn't running at 99% load, turn up the settings until it is and you are no longer bottlenecked by the CPU but by the GPU performance. This is why you see chips like the AMD FX series that matches intel evenly at high resolutions such as 2560x1600 but at lower resolutions where the CPU processing ability becomes more apparent (more FPS, more demand from the GPU for data through the CPU) things like the i5 and i7 manage to pull away.

Depending on the game your CPU may be teh limiting factor, however if you are getting smooth playable frame rates it really doesnt matter either way. Playable equals WIN don't get caught up in the whole "Bottleneck" thing , as long as your getting 60fps or close to it and things are smooth! thumb.gif

PS: I can't possibly see a situation where an overclocked 955 will hold back a game so much its not playable!

I agree, which is why I hate that term. The only reason I would look at it is if I was not going to update the CPU sometime down the road, then it would not make sense to get a graphics card much more powerful in proportion to the rest of the rig. If its playable to you then you've met your goal.

However, time has passed (2 1/2 years since build date) and I was hoping to upgrade my GPU to the new Nvidia GTX 670 from my ATI 5850 to increase gaming performance. Here is a list of the games I am currently playing: Total War Series (anxiously awaiting Rome 2), Battlefield 3, Skyrim, Fallout; New Vegas, and Civ 5 all @ 1920x1080
Current specs are as follows:
CPU- AMD x4 955 @ 3.6 GHZ -C3 revision-stock voltage (1.4)
CPU COOLER- XIGMATEK HDT-SI283
MOBO- ASUS M4A79XTD EVO AM3
RAM- 4GB G.SKILL DDR3 1600
GPU- GIGABYTE ATI 5850 1GB
PSU- CORSAIR TX-750 watt
I was initially going to purchase the GTX 670 but then I heard it may be bottlenecked by my CPU. So I began looking for deals on a CPU and MOBO and Microcenter is offering a I5 2500k + ASUS P8Z77-V LX Socket 1155 MOBO @ $250 after a $20 dollar rebate. This looks like a great deal considering a similiar offer from Newegg would be $300+.
So my question to you guys would be: Should I go ahead and purchase the GTX 670 at $400 or should I get the i5 2500k + MOBO for $250?


first of all why buy a new mobo and cpu ? do you want to spend that much amount to increase your FPS ? remember before boars + chips there are other way increasing your FPS .

i do have 955be... 670 will be fine at stock... and its abit obv your getting better performance with a i7 lol its a better chip obv... also you was having problems with your 5850 cf ? well that could of been your gpu as my 5780 CF were working fine on all games ( didnt have them for too long ).

Not problems, just poor performance. I had 4850CF before that and they were fine but the 955 wasn't fast enough for 5850 CF in some games. A 670 at stock is faster than 5850CF by a decent margin.

What do you mean poor performance? Just how much FPS would I lose in games like BF3 and Shogun 2: Total War?

What? don't worry about it, Phenom II is still a good gaming CPU. If you have an AM3+ platform you should wait for at least a Pile-driver CPU before upgrading. Sure sandy bridge and Ivy bridge are better clock by clock but, especially in benchmarks, but the Phenom II hold its own in multimedia - floating point calculations, just as you would like it when playing games:) You fine with any single card u can get right now

Some answers here for you,

You will still get good fps with a gtx 670 and a 955 BE, Buying a new gpu right now will be better than spending money on a new cpu/motherboard, Although it would be a good idea to upgrade the cpu & board maybe next gen thumb.gif

Good decision. But don't wait for the HD 7950 cards to fall in price. AMD is readying the Radeon HD 7950 Ghz edition to perform better at stock with GTX 670. So the lower prices are to clear stock for the upcoming Radeon HD 7950 Ghz edition which will retail at USD 400 and compete with GTX 670 (similar to Radeon HD 7970 Ghz selling at USD 500 and competing with GTX 680).

http://hexus.net/tech/news/graphics/42089-is-amd-getting-ready-launch-radeon-hd-7950-ghz-edition/

But if you are overclocking HD 7950 is competitive with GTX 670. So why pay any more when you can grab a HD 7950 OC for as low as USD 310 after rebate.

You have to wait for the card to come back to stock. Obviously with these kind of prices that card is going to be a hot deal. thumb.gif

And yeah the Phenom II X4 955 is good enough. Just run the CPU at 3.8 Ghz to not bottleneck the GPU.
