My friend is looking for a power supply to run the 5850 that im currently using as it'll be his, but hes lacking a quality and required wattage power supply to run it. Both options are the 600watt versions of the GS and CX series psus, i was looking at a psu tier chart on neweggs forums, showing the GS above the CX. The price difference is only $10 and the tx series is $20 more from the cx and $10 more than the gs. I know the tx will be better but hes on a budget, so would is the gs slightly better quality? and worth the extra $10? i mean it does have led lights lol but thats the only visual difference lol
