am not really looking for the"chipest" one
as far as i know the best chips out there now are the
680i 965 and the 97x( hope i got the names right)
still there are many mb that use this chips if u can recomend one or 2 will be greet
1. Boards on nVidia's 680i chipset seem OK (ppl say EVGA revA1 is the best between 680i mobos). Those 680i also support SLI (if you need that, although I'll make a guess you don't).
2. Intel's 975x seems to overclock, but less compared to 965p. Ppl went mostly for 965p anyway.
3. Boards on Intels 965p are already long enough on the market - kitchenshark board and its "sisters" from Gigagyte seem to have good reviews indeed. Mobos on 965p will not support new generation of Intel processors ("Penryns"/Wolfdales in fact) set to appear in autumn - but do you actually intend to upgrade in the nearest future, say in a half-year, or a year to those "Penryns"/Wolfdales?
4. Evevn if you're not looking for new processors in fall and especially if you are not looking for CrossFire or SLI, why not a board on Intels newest chipset for the moment - P35 (which is set to replace the 965p) and that will support Wolfdales. The minus - these are, of course, more expensive. I believe again that Gigabyte is a good stable choice - new P35's have solid capacitors, better power management, such boards are more stable and should last longer.
5. You can wait more until Intel comes out with 38x chipset later this year and it will support CrossFire, but do you need that when 965P and p35 already perform well enough?
EVGA680i or Gigabyte 965p boards or their p35s are all good boards AS IT SEEMS. Tom's hardware is preparing a review of the P35 boards with DDR2.
The review with DDR3 is already on the Tom's Hardware (shgould help orient with DDR2 boards in fact) -
Pipe Dreams: Six P35-DDR3 Motherboards Compared
You saw I agreed with Gigayte options - well, I am not a Giga fan, but I just bought my first board from them - a p35-ds4 - I took it for a limited OC, for sm Office & some gaming [the VGA is more important here though] and I'm quite happy. !Be aware that DS4 has a "huge" heatsink on the North Bridge and one should be carefull to choose a cooler that will fit!
As for the less expensive but still quite well performing - as far as I undertsand the "smallest sister" on P35 (Gigabyte P35-DS3) also has a good money-performance ratio (less $, close performance to "middle" group). I'd say for less money - 965p-ds3p with older chipset or p35-ds3 with newer chpset. For more money, I don't know for sure (my DS4 is fine), but see again that test of boards I mentioned above.
