Hey there guys,
I am looking for a bit of advice. My current system is athlon x4 635 with geforce gt 220 and a cheap 450w psu with 20A on 12v rails. I game at 1368 x 768 resolution and don't need uber performance for highest settings/AA and stuff. Since my budget at this time is quite limited I'm looking to get only a gpu for now and upgrade the rest later. Here in the UK I can get XFX/Gigabyte 7770 or XFX 6850 for about 100 pounds. I read that 6850 is slightly faster but also slightly more power hungry. I will get a decent psu in a month or two but will it work for me till then with 6850? I can't decide if 6850 is faster by enough to warrant a new psu right a way, I would really prefer to buy it a little later. Any advice appreciated.
