Thanks for an excellent post.
I looked up the GX270 on the Dell site at it seems to range from :
--Intel Celeron 2.40GHz/533MHz front side bus, 256K L2 cache
--IntelÂ® PentiumÂ® 4 with Hyper-Threading1 technology w/ 3.2GHz/800MHz front side bus, 1MB advanced transfer cache
Seems like a big range. Have you had success with the lower end GX270 or do you need closer to the top end of the line? Any other minimums on the GX270 configuration you could offer would be helpful, too.
