so do u prefre gigabyte and biostar only or I should look for asus but with that chipset
with a Nforce chipset, a Phenom II will be slower than a Athlon II X2. trust me. all those features may look useless but in day to day computing they come more handy than USB 3.0, Sata 3.0 or Xfire, all solid caps, etc.
what u all suggest best mb for mine config
phenim x4
motherboard still to decide
2gb ddr3 @ 2600
500gb WD @ 2250
lg dvd writer @ 950
Logitech combo @ 700
zebronics bijli @ 1500
pls suggest monitor with very good colors and resolution of 1600 x 900 and most importantly less then 6k
below 6k? for that resolution, the monitor must be a 20". Dell/LG/Benq/Samsung don't have any under 6.5k (minimum). so AOC or Acer you can try.
for motherboard, take any board based on 785 or 880G (thats will come under 6k). but if going with Asus, get it locally cause Asus have several problems with their boards so if you encounter one, you can change it soon.
PS: why are you going for Phenom IIs? if not into encoding or so, an Athlon II X4 will perform equally good.
