Not that impressive? It's a budget system. Naturally it's not going to have quad-SLI 7950GX2's and an uber leet PhysX card.
It's a budget system with a fast processor. It's not supposed to be impressive and an uber leet gamer computer. It's a fast computer on a budget. I'm sorry if you weren't impressed by the price tag/componant value, but to say its not a fast system-look at the specs is stating the obvious.
