Hi guys--I recently upgraded to XP Pro from Windows ME and got everything functioning pretty well, but my hard disk(s) are thrashing around quite a bit, probably b/c I've only got 128 meg of memory. I've got a 1.3 ghz p4 w/ GeForce 2 Ultra w/64 meg of video ram and 2 hard drives. Is 256 meg ok or should I bite the bullet and go for 512?? I've got the 800mhz Rambus--the good stuff, but my games run like crap now compared to how they ran on ME--especially Max Payne and Sacrifice. Any suggestions? Also, should I consider a RAID setup in the future to improve performance? Perhaps a GeForce 3 as well?? Thanks in advance...
