im building a new pc and decided to get my gpu first. 4 days ago i got my 670 knowing it should improve my fps by an ton and i expected there to be somewhat a bottleneck because i use a core 2 duo 2.4ghz and 2gb of ram.

Skyrim, torchlight 2 and Race Driver Grid ran smoothly at 40-60 fps with my 8800 gt. I get 15-40 fps with the gtx 670 , it should at least be getting close to 60.

At first i thought it was the cpu, but then i realized that doesn't make any sense because my 8800 gt ran just fine with the same cpu. Then i thought maybe it was my psu not meeting its requirements. I crossed that off because in the past i ran a gtx 460 and prior to that two 8800 gts sli both setups required 2 x 6 pins and require watts somewhere close to a gtx 670.

I have already done clean install the latest drivers and even tested older and new beta drivers, I have disabled power saving mode in nvidia control pannel and energy saving modes in bios too.

so, my set up:

Windows 7
Gigabyte G31M-ES2L
Intel Core 2 duo 6600@2.40GHz 2 CPUs, ~2.4GHz
gskill 2048MB RAM
NVIDIA GeForce GTX 670 2gb
antec 600w psu

here are some benchmarks:

Max FPS: 32.8

The msi gtx 670 could get up 132.2 max fps when overclocked and i know that the cpu is the cause of the low min fps. So, those results were kinda expected but why cant i get those results in a gaming app it just doesnt make sense that my evga 8800 gt performs better than the msi gtx 670. What do you guys think could cause this kind of behavior? That's the main question I'm asking. Because im going to be replacing all other parts of my pc next week but I dont know if I need to RMA my card or not.


thanks for any help in advance

Your CPU is bottlenecking the 670 and will not allow the 670 to fully utlize itself. Yes, it's an intel, no, it's not invincible.

It's your CPU, AND THAT RAM! 2Gb? Upgrade your chipset to a quad core at Minimum with 4Gb DDR3 RAM. Buy an i5 or FX 4300. You're REALLY bottlenecking that GPU!

You could even go with a Intel Pentium G860 3.0GHz for $75 to start with and upgrade to a i5 later. Your not going to get the most out of the GTX 670 until you upgrade the CPU and I'd go with at least 4GB, 8GB if your O/S is 64bit.
