Admittedly, I'm coming pretty late to the party when it comes to finally having a desktop PC capable of running modern games. The entry cost seemed exorbitant, the specs always shifted and it appeared that support for PC-only gaming was waning.
Well, two out of three.
Building a PC from scratch lets you manage the cost quite well. I have a decent processor and a medium level GPU. I think the single biggest cost was my monitor at $120, so it's not bad on the wallet.
However, it seems like you need to have faith that everything will work together well. On paper, I seem to have a respectable rig, but Crysis- while looking nice and going along at a 30+ framerate- just seems to make it run like crap.
This single game alone has caused more error messages than anything else I've thrown at my PC, including a wonderfully heart-attack inducing system reset. I get the impression it's always been pretty buggy, patched or unpatched, but this is taking the piss.
Metro 2033? Runs fine- better than I expected. My old laptop had a GTX 260M and it felt like it was going to die from heat exhaustion. Comparably, my HD 4670 is running pretty cool- it hasn't even broke the 40c mark yet.
New games seem to be harder to find. The release schedule for PC gaming is as anemic as the PSP's.
I love my new PC. I'm just not sure that I'm ready to rely on it completely for gaming yet though.
