Pros: ----- CPU:AMD 4800+ / AMD FX-57 Mainboard: ASUS A8N32-SLI Hard Drives: WD Raptor 74GB RAM: 2 512MB Kingston HyperX PC3200 Power: X-Connect 550W Modular Unit ----- Excellent single card solution. 3DMark 05 benchmark of 10556 w/AMD 4800+ Dual Core. 11666 w/AMD FX-57. (Tried both CPU's)

Cons: 1) Does not work as Quad GPU SLI solution. 2) 2 cards at the same time causes nothing but jitters, freezes and blue screens. 3) Quote from manufactures website "* Please be noticed that one motherboard can only support one EN7800GT DUAL/2DHTV/512M". 3) No directions for Quad GPU SLI (Not supported) in the manual.

Overall Review: Testing: I purchased 1 card first and found it to work well. I ordered a 2nd card to see if I could get it to work in Quad GPU SLI mode. Hoping I would have better luck than was reported on tomshardware.com. What I experienced was almost a carbon copy of their issues. I could get 3 GPU's to show up just like they did. What tomshardware.com did not mention which may have something to do with only 3 GPU's showing up is that after removing 1 of the dual cards and leaving only 1 in the top slot only 1 GPU was recognised. By taking the same card and moving it to the 2nd slot 2 GPU's were recognised. Hence only 3 GPU's recognised by the system when both cards are installed. The mainboard documentation states that you may use either slot when using a single card. I found this not to be true of this card. Only 1 GPU for the top slot and 2 GPUs for the bottom. Thought there may be something wrong with the mainboard. Tried another. Same results.
