GeForce 7900 Battle: GT vs. GS
With equivalent stock clock speeds and potential 14% and 20% advantages in vertex and pixel processing respectively, we have the opportunity to better understand how G71 scales with parallelism. The following graphs are percent increases in performance from the 7900 GS to the 7900 GT for teach game at each resolution tested.
800 x 600 1024 x 768 1280x1024 1600x1200 1920x1440
The 7900 GT shows at most a 15% performance improvement over the 7900 GS in our testing. The largest performance improvement is under Oblivion at a relatively low resolution. Most of the biggest improvements seem to appear at 1024x768. As we increase resolutions, we become more bandwidth limited, and with both cards offering the same amount and speed of memory the scores begin to tighten up. Interestingly, Half-Life 2 shows zero performance difference between the GS and GT at higher resolutions. These cards are by no means CPU bound under such conditions, so we seem to have run into a bandwidth bottleneck.

Woot had this card for $139 a few weeks ago. So glad I jumped!artifex - Thursday, September 7, 2006 - link
I wish I'd bought 3 and sold them on eBay. Instead, I bought 0. :(http://www.woot.com/blog/BlogEntry.aspx?BlogEntryI...">woot entry

I dunno the situation in the US, but Europe is seeing an interesting war. We have 7900GT's costing 230€, right above there is the X1900XT 256mb at 244€ and the X1900XT 512mb at 280€, with the overclocked 7900GT's overlapping in price with the X1900XT's.Check it on www.alternate.de for example.
At these prices, the X1900XT's are a pretty sweet deal, and warrant the little extra money paid over the 7900GT imho.

just to be clear, those are the minimum prices found, in general you have about price parity between the GT's and XT 256mb, with a few superclocked cards costing as much or more as the XT 512mb...Incredible value in the 200-300€/$ range imho, with cards that just months ago were in the 300-500€/$ range

The concluding paragraphs on pages 4 and 5 are identical (i.e., the proper paragraph is missing for the XFX 480M Extreme vs. Stock Performance section).DerekWilson - Wednesday, September 6, 2006 - link
thanks, fixedSpoelie - Wednesday, September 6, 2006 - link
there's also a layout error in the table on page 9TheLiberalTruth - Wednesday, September 6, 2006 - link
I don't know if it's just me or what, but I can't get any page from this article after 1 to load. :\peldor - Wednesday, September 6, 2006 - link
The BFG 7600GT is down to $115 after rebate at Newegg.
