Why? is there something the matter with your KT7? I personally think that the KT7 is a fantastic board for overclocking and performance tweaking. Mine has been nothing but stable, and I have had no complaints from the 5 customer's that I have built systems for with the KT7 non-RAID. I think many people that are trading in their KT7's just because of all of this K7T Pro2A hype, that are not having trouble with their KT7 to begin with, are not going to be happy in comparison. I do not use ABIT boards in the majority of my Socket A system builds, since my customer's are not interested in overclocking. I use the TYAN Trinity KT for it's excellent stability, and 3 year warranty.
Myself, I love to have as much control over my performance settings as possible, and chose the ABIT KT7. I like MSI boards, I have used many Slot A K7 Pro's and MSI P3 mobos.
Just to see for myself, and do a comparison, I ordered a K7T Pro2A from John. I am going to put it to the test, and run Winstone Content Creation, Sandra 2001 Pro, and all other "full tilt boogie" benchmarks compared to my KT7. I enjoy combination multiplier/FSB overclocking, and running my RAM at 144-150MHz. I will see if the MSI can do that. Right now, I am Prime95 Torture test stable at 112/37 + 1 = 113FSB with my RAM at 150MHz CAS2 Turbo, and have been for 4 days.
I will be the first to admit if the K7T Pro2A is a better performer than my KT7, and will install it in my box if it is. I just do not think it will be. I will post the full results of my "real world" comparison testing in a couple of weeks.
If there is nothing wrong with your KT7, there is no reason at all to trade it for another board IMHO.
