Compaq and HP are two brands owned by HP, and from a reliability standpoint are going to be identical.

Judging from the results in PC Magazine's 20th annual service and reliability survey of its customers, Dell is a bit more reliable than HP, but not by much. Both brands have their share of problems - the only major brand that does better than both in PC desktops is Sony.

Of those three, definitely Dell. HP and Compaq will never meet the quality and functionality of a Dell.
Compaq is a type of HP. But to answer your question compaqs are a little on the slow side, they are decent computers for there costs. HPs are nice but they are designed weird. Go for the HP I have never had a dell before I have no idea what they are like.
ive had a dell and compaq..

they both work really well and i would drop hp. but other then that i would go with dell or compaq.
If you are buying a desktop computer then if your budget is between $500-$1000... then buy a compaq... but just make sure that your graphics card has more than a 64mb dedicated memory (this will mean better graphics when playing games) This is not RAM or Hard disk space -- this is graphics memory so don't confuse these things... =)
