7800gtx 512 xxx benchmarks

[newm]

does anybody now what scores you should be getting with 2x7800gtx 512 XXX editions?

I already had an XXX and I got a normal gtx by accident last week which when the two were in SLi benchmarked 13500 in 3DMark05.

I managed to swap it for another XXX and now it only scores 12400 odd.

I have uninstalled/reinstalled the drivers a few times and the score stays around the same.

Does anybody know what this might be down to?

I have read the 7800GTX review on Guru3d and it said their scores were around 11500.

SLI in 3dMark05 is CPU limited so your score will vary with your CPU clock as well.

but i dont understand why one XXX and one normal GTX is quicker than two XXXs on the same PC

i think its a driver issue, ive overclocked it by 5mhz on the core and now get 1500 more points....
