I really can't decide which to do. It seems that almost any game I want to play comes out on both, and the ps3 is wayy cheaper. Even MMOs are driftig towards console releases.
But for some reason I am itching to build a gaming pc.
What do you guys think?
I have a 27" iMac i5 Quad Core and an Xbox 360. Unless you're interested in the fistful of PS3 exclusive titles, the Xbox is the MUCH better console: Better graphics(yes!), better game performance(yes!), more games.
Games simply are not programmed in a way that they can take advantage of a myriad of processor cores, and that simple fact of life makes the PS3 a hardware design failure. That's what you get when you let a marketing department make engineering and design choices. The Xbox 360 has fewer, but MUCH faster processor cores, thus games simply perform better on the Xbox 360 hardware. Actually, the Xbox 360 is a Triple-Core PowerPC G5 running at 3.2 GHz -- a real beast.
When there was still an officially supported Linux port available for the PS3, the PS3 was very interesting for supercomputing tasks - you could build a very cheap high performance cluster with those gadgets. That was what she was really good for. But for gaming, the PS3 is only the second best console on the market. Unless, of course, you also want to use her as a BluRay player.
But since both consoles are cheap, it won't hurt you too much to just buy them both. But if you have to choose between the Xbox 360 or the PS3 version of the game, the Xbox 360 version is usually the better choice.
A gaming PC is only necessary if you want to play something like the STALKER or CRYSIS games on the highest resolution at a maximum frame rate. If you can live with average frame rates, then you can also play those games on any current iMac.
I used to be a heavy player of First Person Shooters, but got tired of the never-ending hardware upgrade race. The Xbox 360 is the best piece of gaming hardware that I've ever bought.
