How much is the best computer?

Stupidly top of the line with triple everything: Thousands.

Now, top of the line but sensible? 1500.

Price/performance? 1200.

Value? 600-800.

Indeed, you can go crazy expensive on a computer but it will gain you nothing. For a computer to play everything at max and continue to do so for a good few years is likely $2000 and even that will likely be over the top of what you need. Sp12 has it about right

Best system is for me, a system which can satisfy my "needs" (this word is important)and "can follow my pocket" (this part is extremely important).

"What I want" is usualy a dangerous term which tends to overbudgetting.

Now go back to you.
What will you do with your rig? Gáming? Normal office work? Audio/Video processing?

How much will spend on the system? (Be reasonable by not saying for example " can I get a complete new system with win7 x64 under $100?")

i gues just for gaming. i have a piece of s*** comp that keeps freezing when playing sc2. The only good thing about it is the processor.. amd phenom ii x4 965 .

mayb i should just buy a new video card? i have a ati radeon hd 4670 1 gig

Well over $9000.

Buying a new graphics card, something relatively cheap compared to a top of the line computer, like the $200 GTX 460 would be able to run SC2 at maximum settings without any problems. Your CPU is good.

You at least need a Radeon HD 57705770 1 GB to play SC2 @ high @ 1920 X 1080.

Better still, if you can afford it, go with the GeForce GTX 460 (Fermi) 1GB

If you just asked that "top of the line everything" out of curiosity, it's understandable. If however, you're wondering if you can actually afford it, you'll probably have another thing coming.

"The world's most expensive personal desktop computer costs $748,720". The range actually starts from $25000. I found this on some website. And my only reaction was WTF!!!   - www.brighthub.com

Make sure you have 4gb of RAM and get a better GPU - 5770 at least, GTX 460 (1gb) or a 5850 (on higher end of budget).

The 5770 should deal with SC2 no problem, i you play other games you may find the extra money spend on a GTX 460 worthwhile, if you play lots of games then the 5850 is worth the buy if you can afford it.

If your motherboard can Crossfire then you may want to go with 5770 (if on tight budget) because it will be fine for SC2 and if you play other games in the future you can adda second 5770. The GTX460 will not be able to have a second card added due to AMD build.

BTW, Just came across this one. Take a look at this crazy $hit. I mean seriously??? - www.tweaktown.com.

Just spending for the heck of it. It's called 'Have Money. Will Spend'
