580 underperforming?

Hey guys,

My brother has just bought himself a custom PC, which has these specs:

Mobo: Gigabyte GA-Z77-D3H
CPU: i5-3570k @ 3.4ghz
RAM: 8GB Corsair Vengeance 1600
GPU: EVGA 570 SC
PSU: 500w Corsair
OP: Win 7 64
Res: 1920x1080

My specs are in my sig


As far as I can see, every aspect of my system either matches or surpasses that of his (I know technically his CPU is better, but my overclock puts the 2500k ahead).

Despite this, his system seems to outperform mine in games, generally by about 3-5 fps (not alot, but enough to give rise to this post imo).

Also, though it obviously doesnt really mean much, his 570 pulls 7.9 on the Windows experience index, whereas my 580 only gets 6.0.

We are both running the latest NVIDIA 301.42 drivers.


Has anyone any suggestions?

Clean your windows. You probably have some nasty stuff running while you're gaming. Is your SSD full?

I had a feeling it might be time for a clean install..

Though I have thought, his board and cpu support PCI-E 3.0, as opposed to my 2.0, could this have an effect?

Edit: Yes, my SSD is full (almost no programs on there, all space is taken by Windows and games)

That's your problem. When SSD fills up, it slows down A LOT. That's why it's advisable to leave at least 30% of free space on it.

PCIe revision does not have any effect at all. Furthermore, GTX 570 does not support PCIe 3.0.

Would a full SSD really decrease fps in games?

In that case Im going to clean install asap haha

Yes it would if it's really full. The games would not be able to read the data from it fast enough so they lag. Furthermore, full SSD is slower than an HDD.
