Thanks for the info.

Regarding gaming, a little offtrack but i wanted to comment since they brought it up.
From my experience their performance are mostly held back by:

1) GPU
2) HDD/DVD
3) CPU

And the conventional wisdom is that its better to get the next generation single card than SLI an older card. SLI in general only provides valuable gains at high resolution and very high anti-aliasing/filtering type settings. Install/Crack your games to the HDD so that you dont have to use the DVD, use an SSD or 10k+ RPM drive for the games you play most often. Watercool and overclock your graphics card(s).
