Hey I'm building my first gaming pc tommorow, and i would like some help and tips on some of my options.

At first I was thinking of buying an alienware, but looking at their pc's I found that they were overpriced and a bit of a gimmick. So I set about trying to bulid my own gaming rig, and so far I feel I've done quite a good job. Below are my specs, and I would like you guys to review my choices, as I don't really know if my rig is powerful enough to run games like empire total war on all high settings.

Intel core i7 processor i7-1920 (4x2.66GHz)

6GB corsair xms3 1333MHz

Asus rampage extreme motherboard

Windows vista 64 bit

750 serial ata hard drive

blu ray reader and burner+ dvd reader and burner with lightscrbe technology

1792mb geforce gtx295 video card

ASUS xonar masterpiece audio card

Antec 1200 gaming case

800 wats

logitech 5.1 digital surround sound system

And a 22" samsung moniter

I'm fairly new to pc gaming so please restrain from harsh comments, I need to know whether this rig is a capable gaming machine and is worth themoney tat i wil pay for it.
