those driver is beta dragon. so when it actually release it gonna improve. for the money you getting tri sli. might as well spend less and get the GTX 280. plus you dont need to stress your PSU if you got single card.
even there are driver issue the GTX 280 still perform brilliantly in any form.
i think this is the question everyone want to know include AMD. but rumuor from a few website say they will drop at the end of this month to encounter the HD4xxx release. because they want to take a big hit at AMD.
