Working at higher frequencies the EVGA is ahead of all the other models of GeForce 8800 GTS 320MB. It is 14% faster than the cards with reference frequencies. The Foxconn and XFX cards with non-overclocked shader processors deliver a 10% performance boost. The Gainward Bliss Golden Sample provides a performance bonus of less than 5% as its GPU frequency is increased by only 27MHz above the default. All these models are considerably slower than the Radeon X1950 XTX especially in terms of minimum speed. This indicates a lack of graphics memory or ineffective memory management.
We are talking about 1280x1024 resolution because the average frame rate of the GeForce 8800 GTS 320MB is hardly higher than 25fps even then. And again, you can’t have comfortable gaming conditions with a min speed of 13-15fps whereas the Radeon X1950 XTX ensures 24fps.
