New PC need GPU

So i just purchased all the parts to my new PC, except for a GPU...i got the following:
Western Digital Raptor WD1500ADFD 150GB 10,000 RPM Serial ATA150 Hard Drive - OEM
Intel Core 2 Duo E6400 Conroe 2.13GHz LGA 775 Processor Model
LG Black E-IDE/ATAPI DVD-ROM Multi Read Drive Model GDR-8164BK - OEM
PHILIPS Combo Drive Black ATAPI/E-IDE Model SPD2850BM/17 - OEM
ASUS P5B Deluxe LGA 775 Intel P965 Express ATX Intel Motherboard - Retail
OCZ Platinum Revision 2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model OCZ2P800R22GK - Retail

So all i need now is a high end GPU, im looking to spend 300-400 anywhere around there, let me know what the best deal is, thanks!

looks like you are getting a 8800gts 640. Make sure that you have a decent psu though you didnt link what you bought in that department.

yea my bad forgot to post PSU, its a brand new Ultra X-Finity / 600-Watt ATX / Dual 80mm Fan / SLI Ready SATA-Ready, you think thats enough? And that was the GPU i was already thinking of getting so cool...
