Buying a PC.. this is what I have got far


ASUS 22" HDMI 1080p monitor - 149.99 *with *delivery!
Microsoft Mouse Laser 5000 - £17 with delivery


xfx 780i Triple SLi Motherboard - 775 socket - £109.99 with delivery

Corsair 4GB (2x2GB) DDR2 1066MHz/PC2-8500 XMS2 Memory CL7 2.0V - £42.99 with Delivery

What I need next is a silent case, a 1050 watt power supply, probably the 285 XFX Graphics card or may go for a 295 - can you run three 295 gtx together and get more than quad sli? I know 2x 295 FXF GTX cards get you quad… what about three?

Also I need a generic DVD rom drive, so generic harddrive space - 350gb and my processor will probably a quad 9000 series…

Anyone have any thoughts or feedback on this system? I want to run CS3 applications and play games. I also want to know on what the best operating system is. If I get XP - Can I still get directx 10 and play and run the latest stuff?
