What is your Power Supply ? u can use PCI-E 2.0 cards and other cards on it,what is your budget ?
wellthe power supply I have know is not even compatable. How ever I will be purchasing at least a 575w or higher sli compatible power supply. my budget is $75.00 - $160.00 for each card new or used.
my research suggest geforce 6600gt 128mb. but those forums were dated back to mid 2005. whats semi modern that will give me something better than 6600gt in sli mode?
