I vote NEITHER. get the MSI 8800GT with the WAY better cooler. It's the one I'd get if I didn't get the GTS. It's clocked at 660MHZ and I'm willing to bet can top 700 if you OC it. The stock GT cooler reallly... um SUCKS!http://www.newegg.com/Product/Product.aspx?Item=N82E16814127329
I never worry about the new cards coming out because they may have "heart stopping" performance, but the price tag is usually the same and you pay premium price for it. You will get a much better deal with a 8800GT.
