So my husband is deployed and I decided to purchase him a new computer. He is a big gamer and is always complaining about his old computer. So....I purchased this on a whim..can you tell me if it will be decent? AMD Athlon 64 X2 6000+ Windsor 3.0GHz Socket AM2 125W Dual-Core Processor 320GB 7200 RPM SATA 3.0Gb/s Hard Drive NVIDIA Geforce 9500GT DDR2 PCI Express w/DUAL-LINK DVI-I+HDTV OUT+CRT Video Card It has windows XP professional, which I was told is better for gaming than Vista. I paid $675 for the unit (it is custom built with a silver alienware case/light kit). Did I over pay...and will he be happy with the computer?
