So you guys might remember me when I posted the problem with my Radeon HD 4890. I had upgraded from a GTS 250 1GB and upgraded to the 4890 expecting a little more FPS, well that wasn't the case. On ALL 3dmark06 and 3dmark vantage benchmarks it performed EXACTLY the same as the GTS 250 1GB that I had, So I got sick of the card and sold it and stuck to Nvidia by downgrading just slightly to a GTX 260 Core 216. I used driver sweeper to sweep all my old drivers and popped this thing in. AGAIN, same performance, No improvement from the GTS 250 1GB or HD 4890. Now here's the thing, The Radeon HD 4890 and the GTX 260 Core 216 have the same power supply requirements and so did the GTS 250 1GB. They all require 500W power supplys and thats exactly how much my PSU is, I have an OCZ StealthXtreme 500w with 36amps on 12v rail which is EXACTLY what the gtx 260 core 216 requires. So I was wondering maybe even my GTS 250 was supposed to perform better ? So my question is CAN IT BE THE PSU ? The cards say that 500w is the minimum but I seem to be getting the same performance on these 3 different cards. I need help finding out EXACTLY what the problem is all my drivers are up to date and if it helps here are my specs.
AMD Phenom II X4 940 @ 3.5GHz
EVGA GeForce GTX 260 Core 216 896MB
Windows 7 Ultimate (32-Bit)
Kingston 4GB DDR2 800 RAM
Can it really be my PSU ? It's like the only thing that seems to make sense, and if it is whats the CHEAPEST/BEST powerful PSU I can get, im tight on money and only have about 60 bucks to waste right at the moment.
