If anyone has ever been part of a team, not just in sports but in any part of life, there is one valuable lesson to learn and that is competition within the team makes the team better.  There are many reasons for this.  Competitiveness pushes individuals on the team to perform at higher levels to ensure their spot on the team.  The ones that don't play a starting role, nevertheless, keep working hard trying to become that next strong player on the team.  In any event, competition is a good thing.  Competition is even better when it comes to computer technology.  With every new piece of technology that gets announced, the top players in the industry flaunt their hardware sporting this new technology.  Who's product is better?  Which company has the better name?  Readers like you then jump to PC Hardware sites and get the scoop on how the new technology performs.  This, my friends, is competition at its best.  These companies are fighting for your hard-earned Benjamins and in doing so are constantly improving the final product.  This can only mean one thing, we are the winners of this ongoing endeavor of the hardware game.

Intel and AMD have been waging battle for some time now obviously and to claim highest performance over all, is the almighty crown.  Intel pushes the envelope with megahertz while AMD offers "slower" processors that perform more efficiently and seem to execute just as quickly.  Motherboard chipsets offer the latest support to get the most speed and efficiency out of these brand spanking new processors.  While dual channel DDR memory support has been all the talk lately, there are still some other chipsets out there that offer similar performance with single channel solutions.  For AMD'ers, Nvidia's nForce2 chipset seems to be the perfect match, but VIA has ideas of their own.  Today we take a look at Gigabyte's motherboard sporting VIA's latest chipset the KT400A.  The Gigabyte 7VAXP-A Ultra has many of the bells and whistles one could hope for.  However, while the KT400A chipset does not offer dual channel DDR memory, it offers what VIA likes to call, a "more efficient" memory architecture which will compete and possibly surpass the nForce2.  Is this it?  Have we found an nForce2 killer?  Grab a seat and get comfy while we give you the inside scoop as to how this motherboard performs.
