Never even noticed this thread. oOo:

Crossfire and sli work well in some games and not as well in others. When you go the dual card route you have to make sure you've a monitor capable of outputting a high res (1600x1200 and higher) make sure you have a good wattage psu 550 - 600+. Also a good cpu is needed, no real point in having a 2.2ghz cpu or something as it'll be more of a bottleneck to the 2 cards. Realistically theres not a cpu out there yet that can provide enough cpu time to make 2 cards run at their fastest but the faster the cpu the better.

Crossfire and sli offer more options in terms of anti aliasing, single ati card max fsa is 6x, with crossfire its 14x

Some games do react pretty oddly to multi card configs, i remember benchmarking doom 3 with 1 card, then with crossfire enabled and the crossfire setup was slower than the single card by 1fps. oOo:

In dod source i get the following:

Im running vista 64bit now so results are probably a little better than they were with xp. Dunno if id go the dual card route again, there are obvious improvements in fps and iq but not really enough to warrant the price of a second card imo.
