i got a dell 630i with dual 9800gt that work great but after two years i think its time to upgrade. i want to make sure the upgrade goes smoothly and want to make sure my psu is up to speed for a dual msi gtx 295 with sli. i have a stock psu of 750w with 4, 12v rails at 18a per rail and i dont really know how to figure out if it can handle the new gpus. any help is greatly appreciated.
Not to familiar with them myself, put my first one together this weekend.
I just wouldn't upgrade to another socket 775 chip at this point.
An I7-860, Asus P7P55D Deluxe, and 4 gigs of OCZ ram is $507 for walk in purchases at Microcenter and then there's $55 worth of rebates, it's what I'm playing with now.
i would go with amd because i know they are cheaper and more powerfull. however first i dont know if they are compatible with my motherboard. second i have heard many issues with software from amd. third is many games are made speciffically for use with nvidia cards. i saw this great article on how nvidia is better and why it is wise to use nvidia. if i can find it ill post it.
