I have narrowed my desktop search down to 2 Gateway computers. The perfect one for my needs seems to be the sx2840. It is a great computer for the price and performance you get. But, since I have $600 in Bestbuy gift cards and they do not carry this Gateway model, I am having a hard time deciding what to do. They do however carry the DX4831-01e for a great price. Both computers seem VERY similar (CNET gave the SX2840 slightly better reviews) so my question is, what is the main difference between these computers? And am I going to be dissapointed with going with the DX instead of the SX??? Any advice would be great.
