the reason is pc 3200 is only $40 at best buy and 2700 is $80. that is the reason

 

Make sure you check Newegg.com before you buy. Their prices tend to be the best around even with shipping, which is always fast BTW. And no stupid rebates you will never receive like at Worst Buy.

 

If you have any doubt, go to www.corsairmemory.com and put your motherboard into the RAM finder. Then go to NewEgg.com and buy that memory. That is your safest and most reliable bet. Besides, Corsair memory is guaranteed for life and performs very well. It is pretty cheap too! BTW, you said $40.00 for PC3200 and $80.00 for PC2700, but how many MB of each. You can get a gigabyte of Corsair TwinX RAM from NewEgg for about $100.
