This build down below saves you some money without cutting back on quality components. But I have to hand it to you.....you did a nice job on that build up above. I didn't know about a few of those combo deals you have posted until just now. "ewiz" is out of Cali, so your going to get taxed on this mobo/cpu combo down below. Not sure about "zipzoomfly".
Also if you do a google on "ewiz coupons" or "ewiz promo codes" you can take another $5 - $15 dollars off that mobo/cpu combo down below.
Since your monitor's resolution is 1680x1050 you could save yourself about $100 by going to an ATI 4850 for your graphics card. The 4850 will play all of today's games with most settings maxed out at your resolution. I recommend this card: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
No sense in spending double the money for a performance increase that you will not use due to your gaming resolution. Plus with the current competitive video card market you will be able to buy a card with double the performance of the 4850 within a 18 months for the other $100.
