I'm looking to spent about $1800 on a new rig, I checked some sites like buyxg.com but seems there is a bit of markup over something like newegg.com. I'm not too comfortable with putting together a machine from scratch (mostly because I don't know what hardware works with what - not that I can't snap everything together, its like legos).

Looking for something like:

i7 2.66Ghz (or 3.0 if I can get it cheap)
12-16GB RAM - 1333 or 1666
2 or 3-way SLI motherboard
1000w PSU
Video cards up in the air - a pair of nvidia 285s, or ATI 5870s. or just one 295GTX
1.5TB whatever hard drive, don't care
64GB SSD for wow

I put together something like that on buyxg.com but it went over $2000 with Win7, and there was no option for 16GB ram (had to jump to 24GB for another grand).

I think I could put the machine together if I knew what parts to buy... can anyone list their rig specs and approx price and maybe I'll just go with that setup?

Thanks
