Pretty good! IMHO... Drop to 4GB of memory. You can always add 4 GB more later at no additional cost compared to buying 8 GB now. Check out MicroCenter if you have one near you. They have that X6 bundled with a MB for $240 after rebate. Also, Black Friday deals have a Blu-ray reader / DVD burner combo drive for $45 after rebate. ...something to consider for an additional $25 over that Lighton. Lastly, if not using that WD Black as a boot drive go with a standard 1TB / 2TB to supplement the OCZ SSD. You won't see the benefits of its speed in that config and the price is a up there with larger capacity drives.
I suggest going with a 955 instead of a 1090T, the main reason is the 1090T isn't the best CPU for it's price point. Get the 955 and save some dough, and also get a cheaper mobo and save some dough. These ways will allow you to upgrade to an even better CPU later and the 955 isn't a slouch.
AMD's Bulldozer is coming out next year so you don't need to spend so much now, save as much as you can to the bare minimum and then just upgrade to Zambezi (8-Core Desktop CPU) It'll be 2x faster than the current line says AMD and compete directly with the current i7's.
I suggest this CPU and this MOBO because the mobo has onboard graphics already so you don't have to get a dedicated card, plus it has USB 3 support and the onboard graphics will run any res, even 1080P.
Um as for your SSD and HDD, change them. The SSD isn't bad but for the price, it's a lot. Plus for much cheaper you can get the A-Data S599 which also has an Sandforce controller, but is cheaper than the Agility 2. It also performs like a Vertex 2.
As for the HDD I recommend getting a Samsung F3, it's a faster drive overall because of the 500gb platter size, but also is cheaper than most Black's per gig. The Samsung F3 500gb is only 55$ and the Samsung F3 1TB is 70$.
I pretty much ordered that setup after no replies for a few days... I think I'll be good to go. Only thing I'm worried about is the OCZ Gold Ram as I bought the 8GB 2x4 just so I'd be solid for a while and when I looked at their help forums there were tons of Gigabyte MB's with X6 1090T's on there with instability issues.
I may send them straight back and get the Gskills. I had my eye on the G Skills the whole time but for some reason went with the OCZ Gold... hope it works. I'll let you know.
