Need Advice! Building System £500 budget

Hi guys, i've got a £500 budget +/- a small amount and basically i'm aiming to build a new system for this price. It wont be the best out there but i hope to make it upgradeable in the future.

The system will mostly be used for gaming but also film editing.

I already have a case but will need a large PSU as the one i currently have is a meer 350W!

I was thinking along the following lines.... (i'm using www.overclockers.co.uk for prices... let me know if there are any cheaper out there!)


Intel Core 2 Quad Pro Q6600 "Energy Efficient SLACR 95W Edition" 2.40GHz (1066FSB) - £152
Gigabyte GA-P35-DS3L Intel P35 (Socket 775) PCI-Express DDR2 Motherboard - £64
Crucial Ballistix 2GB (2x1GB) DDR2 PC2-8500C5 1066MHz Dual Channel Kit - £77
Be Quiet! Straight Power 700W ATX2.2 SLI Compliant PSU - £80
Zalman CNPS7500-CU CPU Cooler - £28
Gainward BLISS GeForce 8800 GT 512MB GDDR3 HDTV/Dual DVI (PCI-Express) - £182

This comes to a total of £ 583, however, i have another problem of only having an ATA harddrive. So i would also need to consider that. I have a DVD/RW already that i can use.

Seagate Barracuda 7200.10 160GB SATA-II 8MB Cache - £36

That would bring the grand total to £619

Any ideas how i can reduce the price or is there a motherboard out there with more than 1 x IDE (So i can use my existing hardrive as well as not having to buy a new SATA DVD/RW which will be future proof and compatible with the new 45nm chips?

Thanks in advance

I myself am currently in the market for a system around that price and i picked out a very similar setup. Only difference was i went with HD3870 (They seem to be a LOT cheaper than 8800GT in the UK atm) with an E4500 as i don't really see the point in quad core atm. Also pairing that with an Antec Sonata III, nice looking case with a decent PSU as standard.
