Low budget high performance i7-920 rig

[reign10057]

This would be my 3rd build but thats over a 10 yr period. Last build and current setup is p4 3.2. Basically looking to build as future proof as possible but as low priced as possible using coupons and rebates. Heres what I got so far and what I am looking at:

Have:
OCZ Vertex Series 60GB SATA II = $165
XFX Radeon HD 4890 Video Card - 1024MB DDR5 = $125
SILVERSTONE ELEMENT 750W st75ef 80 P = $61.05
Seagate Barracuda 7200.12 500GB = $31.69

Looking at:
i7-920 = 199.99
AZZA Fantom 900 = 68.59
OCZ Gold DDR3 PC1600 6GB =119.99

Then either
ASRock X58 Extreme for $159 or
ASUS p6t se for $152.59

Also need recommendations for wireless N adapter or card and keyboard and mouse for gaming but "bang for the buck"
and I could get an extra Seagate for $43 and extra 4890 for $150 but thinking 1 of each is good for now and waiting for prices to come down on video cards again.

Any recommendations on MB and why? Ram good? Would like to use my Samsung 61" 1080p as the display for this, any problems with that

Get a USB wireless adapter. Far easier to deal with if there is a problem and its easily portable.

"Bang for Buck" a cheap usb keyboard and wired optical mouse for under $25. Gaming mice and keyboards only give you a small advantage (assuming you actually make full use of them) for about 8 times the price.
