Is this a good setup??

[Badkarma]

Hi all, need some help determining if this is a good upgrade

Thermaltake Soprano (windowed) = £50.47
MSI K8N Neo4 Platinum nForce4 Ultra Motherboard = £76.32
AMD 64 3700+ San Diego Core (OEM) = £149.17
Gigabyte G-Power Pro CPU Cooler = £26.97
Total minus gfx = £302.93 incl tax

now I cant decide which is better to go for...the 7800GT 512mb Goes like hell or the XFX 7900gt 256mb extreme (would say the latter)

need recomendations on a PSU and possibly RAM (pref 2Gb)

keeping my dvd writer, HDD and soundcard. Does the motherboard support High Density Ram...if not need new RAM

All help appreciated

thanx for the fast reply, heard that not many progs support dual core at the moment and that sticking with single would be best..but will look into it
