Can anybody break down the basic real-world performance differences between these two cards? I know its 325/290 vs. the Pro's 340/340, and I've also heard here and there that its performance is similar to a 9700 Pro. I also heard they can be oc'd to perform the same as the Pro. Basically, if I want to upgrade to a good GPU for DX9 apps is the 9800 non-Pro a good deal? I found a few brand-new on eBay for between $185-230, and I'm trying to figure out if this is a good bang-for-the-buck card.
