Pros: Worked with mixed sized memory added it to a computer that had 512MB running XP. Made computer much faster and I got a $10 tip from my tia.

Cons: none.

Pros: The newer card has a larger silver aluminium finned heatsink. The newer card runs the graphics clock at 800MHz, processor clock at 1.6GHz & memory clock at 2GHz. It runs about 2-4C hotter, but with about 200 RPM less fan speed. BIOS ver 70.04.1B.00.02 SLI works games look and play great.

Cons: Slightly mismatched "identical" cards running different. Manufacturer doesn't mention any updates that I have found. The older cards have smaller black heatsink. The old card runs the graphics clock at 700MHz, processor clock @ 1.4GHz & memory clock at 1.8 GHz. It runs cooler with more fan speed. BIOS ver 70.04.13.00.01. So even if you plan on buying 1 now and 1 later they still may not match.

Overall Review: I purchased one of these back in October of 2010 with a MSI NF980G65 3 way SLI board with the hopes of only using the two outboard SLI ports to allow some air space between the cards. I finally purchased a second card in January of 2011. I had to ditch the MSI SLI bridge because it caused all games to flash constantly. I ordered a EVGA SLI bridge and that fixed the problem. I am using MSI afterburner with a G15 keyboard LCD showing GPU stats during gaming. So far I haven't gotten them over 60C.
