FileFront Forums - Upgrade of Guild War 2

Hello all Forum members, I bought this computer a few years ago because my older one couldn't handle the massive fights in Darkfall (few hundred people on screen) and it did the job wonderfully. My love for large scale warfare has me in the exact same situation with GW2. I can play on high settings with playable FPS while leveling solo/small group but when I do large events (30-50 people) it gets pretty sluggish and when I do World v World (80+) it gets pretty bad. I can still kind of function but yuck, on best performance settings.

Intel Core 2 Duo CPU E8500
4GB
DX11
Windows 7 ultimate 64
Nvidia Geforce GTX 260
1280x1024 resolution

my budget is as cheap yet effective as possible. My mission is to get acceptable/good frame rates during large scale fights on low settings. I couldn't care less about graphics.

Thanks.
