So I have these two computers, and was going to give one away to someone who needs a computer. In terms of spec I'd say the Dimensions E310 is better than the Optiplex 270. But the optiplex 270 seems to have way more connectivity inside. Basically I want to keep the fastest computer. Here is the specs for the Dell Dimensions E310 and Dell Optiplex GX270. I have installed 2GB memory in the Dimensions E310, and the Optiplex GX270 has 512md memory. Both are pentium 4, but the Optiplex is Celeron and the Dimensions is Pentium 4 HT. Right now the Dimensions is quite speed because of the added 2GB memory and the Optiplex is slow because of the 512mb memory. But if the Optiplex had 2Gb memory would it be faster than the Dimensions. Also the E310 is using SATA for the harddrive and the Gx270 is using IDE. Which one should I keep?
