Slightly over i know but it has two gigs of ram (which will keep the system running smooth and any games)
The GTO2 is a great card, without any modding skill, you just need to flash the card (there is a guide below which you find in over-clockers) and will give you a x850xt which is capable of running games fine and the case will help keep noise levels low
