happy new year guys. Im currently using Gigabyte 9800gtx+ which is 1GB and i wanted to buy XFX 9800gtx+ 512mb to do SLI. So here is the Q, is that both working even though the one is 1GB and another is 512mb? thx for reading anyway. =)

another SLI user,currently using dual gigabyte 9800gtx+ and my experience is, not every game could possible get a good performance when enable SLI mode. Intially i predicted it is like double performance when playing any game in SLI mode. well, there are 2 games that seems to get a quite good performance which are CRYSIS warhead and FARCRY2.

SLI mode
For crysis warhead, running at 1440x900, max setting but without AA runs at average 35-40fps. (Disable SLI >> 20-25fps)

For farcry2, running at 1440x900, ultra high with AAx4 runs at average 60fps. (Disable SLI >> 40-45fps)

So far the rest of the game does not seems like increase that much performance when enable SLI mode somemore drop.
