GPU and wireless card

[Hawkesbury]

Hello,

My friend is buying the following set up 2nd hand (3 months old) and requires a GFX card.

AMD Phenom II X2 Dual Core 550
ASUS M3N78-EM Mobo
Kingston HyperX 4GB DDR2 8500C5
LG GH22NS40 22x DVD±RW
500 GB Samsung HD502HI EcoGreen F2
Antec 300 case
Nexus 430 PSU

Will the PSU be able to power a 5770 and if so of the current bunch at around £120 is one better than the others? I was thinking the Asus purely for the 3 year warranty.

also he requires a wireless card for the PC is there any difference between the brands in terms of performance?

Will be running windows 7.
Thanks in advance!

The PSU will work fine and there isn't any difference between the HD5770s except the warranty and the cooler.

PSU will work although might be verging on being close to not being quite enough

in terms of wireless cards they are all somewhat of a much of a muchness. Get a brand name one and check their website for driver support.
