Re: PCI-E x16 running at x1 on new GTX 280
I did try it out in crysis and clear sky, both of which had performance significantly worse than my 8800gts 320. I'm disinclined to think it's a motherboard problem as my 8800 is working fine right now. It stated 'pci-e 16x @ 1x' everywhere I looked (GPU-Z, nvidia panel).
I RMA'ed it last week, i'll post back when I get the new one.
4GB Kingston HyperX PC2 8500
EVGA GTX 260 216
Intel X25M G2 160GB SSD
X-Fi Xtreme Music
Corsair TX 650
