so im thinking of buying a new graphic card and i have one in mind PNY the GeForce GTX 260 and on tigerdirect it sais;
ESSENTIAL SPECS:
• Interface Type: PCI Express 2.0 x16 (PCIe 1.0 Compatible)

and i only have a PCI express 1 slots so i was wondering, when it sais PCIe 1.0 compatible does that mean i can use it? and will it work properly?
