GTX 460 question bottleneck

What Intel CPU is it? I doubt it'd bottleneck the GTX 460 regardless, but I'm just curious. Also, what PSU model do you have specifically? 500 W is for the whole system, and normally nVidia recommends a greater wattage than in reality just to compensate for those using cheaper PSUs which don't actually deliver anywhere near 500 W. Check your PSU model. RAM is fine, 4 GB wouldn't be a bottleneck.

intel core 2 quad q8400 yorkfield.

i couldnt figure out what the hell the psu said other than 80% efficient. so i took a pic

The Q8000 series aren't the best C2Qs, but they're far more than enough I guess. Being an 80+ PSU means it's not a too-low end class PSU. It delivers 30 A in total to the 12 V rail of your system, 360 W max for the 12 V rail which should be sufficient for a C2Q Q8400 and GTX 460 system. I'd try and avoid overclocking though, just to be safe.

Looks fine to me the CPU is plenty for the 460.

YOur CPU has enough power. But your PSU... It´s a quality PSU, that´s true, but I would go for a ATI 5770.

what do you mean its a quality psu. and i have made my mind with the GTX 460. its the best for the value
