I used to have an Asus 6670 DDR5 and it runs the game ok. The problem is the game is VERY CPU ran. If your cpu sucks you will run at 15fps and your gpu will bottleneck. GW2 requires pretty expensive parts. You should think about buying a custom computer with either a Fx-8350 (or 8320) or an i5 3570k (or 2500k) The cpu will run you around $200, next is the motherboard. Amd motherboards are cheaper so I would go amd, but its up to you. Cases run $30 to $120. A good graphics card will run you $120 - $300 The HIS 7850 is $170 on newegg (GOOD DEAL) You will only need a 500 watt power supply unless your overclocking then go 600 watt. Most people over buy on power supplies. You will only need 4gb of ram, get a corsair blue for about $25 (make sure its 1600 mhz) Western makes cheap and very good hard drives. You will spend about $80 on a 1Tb hard drive. These are just some ideas, that system would run the game at 60fps max settings easy. That's a best case system, so just work down from this. Your going to spend around $500 - $800 Just look around for what fits you.
