Oh the ps3 has 8 cpu's while the xbox has 3, they both are 3.2ghz tho.
to me that ps3 seems to be quite a monster but this is my thought and im still looking into whether i should upgrade my pc or for the same price get ps3
LOL where did you hear that.. the CPU part I mean...I think you might be refering to the SPE's that the PS3 have, of which there are 7.
Now anyway to answer your first question, I've been a hardcore gamer most of my life, spending a minimum of 3-4 hours a day during the week on my PC playing anything from online RPG's to old retro 1980 arcade games. 2 months ago I bought myself an Xbox because of a game due to be released called Mass Effect that I wanted to play, and is only being release on the XBOX.
I've never looked back once, I still play on my PC, but the Xbox is a nice change and the games are really incredible. The Live features of the Xbox also makes it really interesting where almost all the games have multi player options to play online. Hell my Wife has even started playing games with me now and we spend quite a bit of time playing together on the XBOX
With regards to the PS3 VS XBOX ... your going to open a can of worms there that you aint going to be able to close again, Everyone will give you pros and cons on both sides.
My take.. is the XBOX 360, at this point it can do much more than the PS3 as its going to take at least 2-3 years for the PS3's full potential to be realised, problem is 3 years in the IT industry is to much of a long wait and who knows what else will be available then. Its much cheaper than the PS3 (you will be looking at closer to 6-8k for it when it lands here btw) and its upgradable. PS3 has its Blue-Ray Drive which currently is not supported by many, its the old VCR vs BETA story, nice thing about the XBOX.. if Blue ray takes off.. Well plug a blue ray drive in.. plain and simple
But dont take my word for it, read some reviews on some of the sites here are two to start you off with
