I got in on a similar deal last month, not bad if you want CoD4, if you plan on selling it expect to only get about $20 out of it.
I was a bit worried about the rebate since it's handled in house by TD/Systemax, but they just recently approved my submission without a bullshit story about my UPC not being included or the form being incomplete.
Also, note that the 256mb cards are clocked at 1.4ghz mem rather than 1.8ghz, so they aren't exactly 8800gt's with half the ram, but still pretty close.
