Best GPU to replace for my current system

[pw38]

Wow I can't make up my mind, I will look out for a MODULAR one as my case has barely any room T_T.

People say that OCZ tends to not be as stable,but this one's $35 on sale..
OCZ ModXStream Pro 600W ATX 20/24PIN SLI Ready Modular Cables 135mm Fan Active PFC Power Supply

So I should rather get a Seasonic Modular $95, and wait for a sale?
Seasonic M12II 620W EPS12V 20/24PIN ATX Power Supply PFC 80+ Bronze Modular 6PIN PCI-E 120MM Fan

I have an OCZ ModXSteam Pro 700W along with a 69501GB and have no issues whatsoever.

madcat you know why i know the 6990 is loud hot and extremely fast?cause i purchased one and i didnt even own it two days and i returned it in favor of a gtx580 hows that for a source,a users own experience is 4x as good as any review link or page wouldnt you think?pick one up and see for yourself till then get off my back

Okay I thought I might as well get a new Case to fit an aftermarket heatsink to OC the Q6600 and non-modular cable management.

I currently ordered:

Case: Coolermaster CM 690 II Advanced ATX Mid Tower Case Black 4X5.25 1X3.5EXT 6X3.5INT *No PSU*

PSU:XFX 550W PRO550W Core Edition Single Rail ATX 12V 44A 24PIN ATX Power Supply 80PLUS Bronze

HSF:Coolermaster Hyper 212 Plus Direct Touch 4 Heatpipe Heatsink AM2 AM3 LGA1366 LGA1155 LGA1156 120MM

So a GTX460 is good enough for this or can I push it and get something more powerful? Assuming I'll OC to 3.2 Ghz once I get the parts...

I think the 6850 is better than gtx 460 1gb.. Awhile ago I had a 6850 and it performs really good...


Considering the responses ive heard, and the price ranges, id probably go with the Sapphire Radeon PCI Express

Yes the AMD HD 6850 is slightly better performer than GTX460, but what I meant to ask was if i get something like the 560ti or 6950 would that bottleneck @ 3.2?

Price/performance completely broken down by the efficiency spreadsheet in sig.
