No need to go for gtx580.
Go for hd7870 instead
Performs better,overclocks better,much lower power consumption.
Go for GTX670. Or HD7870 below that.
@saiyaman Go for HD 7870. as far as I know most of benchmarks are neck and neck and the newer driver updates help the performance of 7870 a lot. The power consumption of the AMD is also lower.
I thought that GTX 580 was better in performance. Looks like I'm wrong. I saw the reviews. Till now I have always used Nvidia based cards and have no idea about Ati.
Should I use a Nvidia card to make use of the PhysX feature?
