If I hadn't seen your budget, I'd have said get neither, get an i5-2500K instead. The 2600K is excellent if you can afford it.
If you've already bought an AM3 board, however, I suppose you could get a Phenom II X4 980 to go with it. Would save you a ton of cash. The 1100T isn't fast enough in general to be recommended above it, and Bulldozer is far too immature plus doesn't offer enough of a performance boost for the extra cash (that board only has a beta BIOS for Bulldozer anyway).
