Well a good and proven DDR board is the Epox 8k7a, and also the Gigabyte 7DX. However I'm not saying that the KG-7 won't be a bad-ass board, in fact it's suppossed to be the best, but what I mean by me not wanting it is that there are going to be new boards by the time I build my rig (Come september), and I think an nforce or an sis735 board should do me a bit better. Now granted you can't get boards made w/ these chips yet, but since I have to wait I decided to wait for these. These are suppossed to be better than the AMD 761 chipset (Which the KG-7 is based on), and on beta boards have already beaten them performance wise (I don't remember any reviews of the nforce chipset being compared to the current mobos, but I'm sure it will beat em out because of all the advancements in the chipset). If you snoop around in some forums, you should be able to find out some information on these boards. So if you're in a hurry try the epox or Gigabyte, but if you want to wait maybe a couple weeks, you can wait for the KG-7, and if you wanna wait longer you might wanna try the nforce or sis735 boards. Now HSF is really dependant on what kind of case you have. You could by the best hsf, and have no good case cooling, and your temps would still be high as hell. You have to have case cooling in order to have effective air movement around your entire pc. Now if you've already taken care of that, then I suggest you buy the sk-6. It's most definitley in the top 3 heatsinks, and with a Y.S. tech 27cfm fan, it'll provide really good cooling for you. If you don't mind the noise, you can try a delta 30cfm, or even a delta 38cfm fan (It whines and sounds like a blow dryer). That Cak is good as well, and I'm not sure about the Cak's cost, but the sk-6 can be bought at kdcomputers.com for $45.00 w/ the delta 30 cfm fan (Oh, and today they have free shipping since it's 4th of July). They might have other one's there as well.
