thanks for your advice again! Im thinking ive got a decent list together now;

Intel Core i7 920 D0 Stepping (SLBEJ) 2.66Ghz (Nehalem) (Socket LGA1366) - Retail - £220.99

Samsung SpinPoint F3 1TB SATA-II 32MB Cache - OEM (HD103SJ) - £64.99
Coolermaster CM-690 Dominator Case - Black - £59.98
Then im going to upgrade the rest of my computer with the following..
Iiyama ProLite E2407HDSD 24" Widescreen LCD Monitor - £159.25
Logitech G11 Gaming Keyboard (967929-0120) - £25.99
Sony Optiarc AD-5240S 24x DVD±RW SATA ReWriter (Black) - £16.99
Cherry M-305 AZURO Wireless Optical Mouse - £9.99
I have two last questions, thank you to everyone that has helped me so far!
1) What would be the best LCD monitor to get the best gaming performance with a 5870 from? I have choosen this one but thats because it was cheap.
Iiyama ProLite E2407HDSD 24" Widescreen LCD Monitor [PLE2407HDSD-B] 24" LCD
2) My favourite game is Football Manager, a game that relies on good RAM, now I have gone with 6GB 1600MHz (as listed above) but would 6GB of 2000MHz make much difference? also would 12GB of 16000MHz see much improvement?
