Kind of depends on how much trouble you want to go to. I have an Athlon TBB running at 2000 MHz (20x 100) on my KT7 (non RAID). There are details about cutting the bridges to get the higher multipliers in older threads.
Otherwise...
There is a 1300MHz (13x 100FSB) TBird listed on Pricewatch.com for $85. However I only paid $50 shipped for my XP.
XPs run on the KT7 even though they are not "supported" by ABIT. But since XPs generally run at 133FSB instead of 100FSB, they will run at 2/3 the MHz listed, unless you change the multiplier. The 1700+ runs at 1467MHz (11x 133), but 11 times 100 is only 1100MHz. You can bump the multiplier up to 12.5 in the KT7 BIOS and it will work.
You can get a /TBB 2100+ which runs at 13x 133, but 13x through 14.5x don't work on XPs with the KT7 (the reason is odd.) But if you reset the CMOS, it WILL end up booting at 20x 100 = 2000Mz. Then you can go into the BIOS and set other multipliers (over 14.5) but you need to reinterpret the settings. For starters, try 7x which gives an actual multiplier of 15x.
5 - no boot (13x)
5.5 - no boot (13.5x)
6 - no boot (14x)
6.5 - (21x)
7 - 15
7.5 - 22
8 - 16
8.5 - 16.5
9 - 17
9.5 - 18
10 - 23
10.5 - 24
11 - no boot
11.5 - 19
12 - no boot
12.5 - 20
The reason for this is that there is one more multiplier bit on XPs, which the KT7 does not have the hardware to change, and this means you only get the higher multipliers for TBBs that are factory set to 13 or higher.
That is all without any cutting or modding.
