I read the 2 page poll you started on the other site... not very informative considering how many prople rated the 7600GO as a "performance" card vs the x1400. They are both low grade cards, the 7600 being slightly better than the x1400.
I have to agree with the previous poster, you have already decided which route you wanted to take. Get your HP & enjoy it! There is no point in most polls because a lot of it is based on bias.
I am biased towards Dell. I have had an HP, did not care for the keyboard config, the performance, or the overall support they provided. Dell has worked out for me. You will surely find people that have purchased a Dell & had a terrible experience & went to HP or another vendor...
Bottom line, get what you want! Enjoy it! If you don't like it then next time you will be able to try something different!
