new upgrade

[djxtc]

hi, I built myself a pc two years ago and i m now considering investing around £800 to make it nice again and ready for windows 7. I mostly use my pc for work and gaming.
This are the components that i have at the moment:

Windows Vista Home Premium 32 oem
ASUSTeK P5K-E
Nvidia Geforce 8800 GTX
2gb corsair ram
Arctic Cooling AC-FRZ-7P Freezer 7 Pro
Antec P182
Intel Core 2 duo E6750
1 Samsung 500GB Hard Drive SATAII 7200rpm 16MB Cache - OEM
Dell 24” (2407FPW)
Arctic Cooling AC-FRZ-7P Freezer 7 Pro
Corsair 620W HX Series Modular PSU


Could anyone please give me some advice on the best way to spend the money to upgrade this computer?
thank you very much in advance

thanks for your advice everyone, i m thinking of going for the *OVERCLOCKED* Intel Core i7 920 D0 Stepping (SLBEJ) 2.66Ghz @ 4.00GHz Max / Gigabyte EX58-UD5 Intel X58 Motherboard / Patriot Viper 6GB DDR3 PC3-12800C8 1600MHz DDR3 Bundle; as i m not very good at overclocking; I also thing that I would like a new case as mine had a few problems and i d like a new one really hehe. Do you think that this bundle is good and also do you have recommendation for a good looking case, thanks

Thank you very much for everyones opinion, much appreaciated and very helpful. I really like the Lian Li PC-7 and have heard very good things about it, now i m just wondering with all the new parts inside the pc, and a new series 5 card when they come out, will my 620W corsair be enouth to support everything? Thanks again very much
