My friend has a HP Pavillion computer (Model a630n):
Intel Pentium 4 520 2800 MHz
Asus PTGD1-LA (3 PCI, 1 PCI-E x16, 4 DDR DIMM, Audio, Video)
512 MB of PC3200 DDR Ram
160GB Hard Drive
300 Watt Power Supply
He wants to be able to play Battlefield 2, WoW and other games on good settings, so I suggested that he gets:
EVGA Geforce 6800GS CO SE PCiE16x
Kingston Dual Channel 512MB PC3200 DDR 400MHz Memory (2 x 256MB)
both total to CDN $369.99
with shipping and tax
However, I then realized that he has a 300W power supply!
Is it possible to upgrade that power supply to something like 450W so he can run that video card keeping in mind that he has limited knowledge of building a computer?
Also, is it hard to replace power supplies?
And finally, do you think that it is a good decision (keeping in mind that he has a $400 CDN dollar budget)?
Thanks in advance, for your help!
