Motherboards GA - N650SLI - DSL4 PCI-E V1?

Hi there, was just tryin to find out if the GA - N650SLI - DSL4 PCI-E is rev1 or 2 i'm sure it's 1 but i'd like to know cos i was thinkin of gettin a 4870x2, which means... new mobo also if it's v1

 

PCI-E v1.1 and v2.0 are interchangeable, which means that they can be used in any combinations, eg v1 mobo + v2 GPU, v2 mobo + v1 GPU, etc... Nowadays graphics cards don't even max out the v1 bus width, and I think it was tested somewhere that there was a 2fps drop when you used the slower bus.

 

Cheers =] what would be the best gfx card for money on this system

CPU E6700 @ 3.2ghz
Mem 2gb pc6400, can easily upgrade to 4gb or even 6 @ 8500
mobo as above,
HDD wd 250 16mb caviar
gfx 7900gtx SLI

for far cry 2 on 1920 * 1200 settingx

 

Dunno, maybe a 4850, or a 4870. Or a GTX260 or a 9800GTX(+).
