Hiya George,
Building a good gaming rig is not easy, I tried myself, and you can google
for the results, it was a pain in the ass.
Problems faced: overheat, dust collection.
Having said that.
The latest and greatest graphics card is the nvidia titan. Even a super
computer was named after it.
However one would have to make sure the power supply can handle it and
perhaps the motherboard as well.
The titan probably gets hot though, so a passively cooled graphics card is
interesting too though they not as powerfull.
Perhaps a mid range card is safest.
Also a good case is needed for ventilation.
You mentioned upgrading an old desktop and then you mention buying a new one
?
I am a bit confused about that.
If truely upgrading have to be carefull that all components can handle it.
If buying a new one, perhaps being a computer from a specialized gaming rig
company is an idea.
Perhaps they can throw it some nice water cooling... or just a decently
designed air cooled PC.
It all depends on the budget
Minecraft is probably not the most demanding game but you also mentioned
overheat of laptop... so you are familiar with the overheat topic
Dell is probably crap, HP is probably crap too... a little bit less crap
though just cheap... at least my mothers HP still running barely... it
little used though... my sister bought a Dell it died
All computers seem to die lately
1.) should I buy from Dell? (I've used them in the past.)
If you lazy perhaps yes, or give Alien Ware a try or so
<- they
selling gaming rigs if I am not mistaken
2.) Which operating system. I was thinking of win8... but now you've
all made me nervous, but I wouold like some newer version of windows
(running XP at home and work.) moslty becasue the kids will be using
the newer version in school. So maybe Win7?
Perhaps wait a bit for the new windows 8.1 operating system.
It would suck having to buy windows 7 with all those services packs and
patches... it would be patching 2 days at least.
Also it's on the way out so not really future ready ?! More and more games
will start focussing on windows 8...
3.) How much memory? I figured 8 or 12G.
It's a bit overkill but always good to have more.
Even my system with 4 GB ram only uses 3.2 and it works fine.
If you want to be future proof get 8GB otherwise spent the money on
something else.
4.) Do I need the fancy graphics cards for gaming? (My thought was I
could let my son pitch in for a better card if that's needed.)
Yes for good gaming a graphics card is needed/essential.
I see more and more games using CUDA, so getting an NVIDIA card would be
wise
plus I am a slight nvidia fan so I may be biased
I hope to have been of some help, trust me it not easy
Bye,
Skybuck.
