Hi, Here goes, Im looking to build a new pc, including monitor etc for around £600- £800. I already have a x800xl, which i'll keep and an antec 450 psu. I have a gig of kingston ram,2x 512 MB PC3200 DDR SDRAM (3.0-3-3-8 @ 200 MHz) which I'd like to keep but will change if necessary. Has anybody got any suggestions of a good build based around an sli mobo (im going to upgrade to this when x800 starts gettin old) and an amd chip. Maybe the 3800 dual core, Thanks for any help guys. Be nice this is my first build.
