I know this is an old thread, but I dont think the OP is really that far off base.
Here is my reasoning:
I currently have an AMD 64 3500+ with a 939 socket. I am running a 7800 GT.
Lets just say I wanted to play Colin McRae: DIRT. My current machien will not run the game well at all.
Id need a new processor first off, and since the 939 socket is not used anymore, ill need a new motherboard. And Since DDR2 is the standard on new motherboards, ill need new memory too. And of course the 8800GTS 320MB. So lets add this all up, using prices from a really popular site.
AMD X2 64 6000+ $170
ASUS nVidia m/B $150
2GB of OCZ DDR2 $120
nVidia 8800GTS 320MB $280
sweet! Ready to go right? No. Not yet. My powersupply is not going to be powerful enough for the new video card, so I need to buy one of those too.
OCZ ModxStream 780w $180.
Ok cool, ready? No, not yet. My new video card supports Directx 10, and so do some of my games!! Guess I better upgrade to Vista so I can utilize this sweet technology..I mean, I paid for it right?
Windows Vista Home Premium OEM $115.00
Ready now?! Ya sure. But half of my applications dont work under Vista. And some of my hardware needs new drivers, which may or may not be available yet. AND Vista eats memory faster than alzheimers, so I should probably get 2 more GBs so that my sweet games still have enough memory for all those fancy textures. And after all that, if im lucky, the game will install and run.
But wait, the game doesnt run, it blue screens. Hmm. So I have to download the latest patch and install that. Ok done. But crap, my joystick doesnt work under Vista, and my older Soundcard wont run EAX under Vista.
So after much frustration, I get the game and all my peripherals working....but the game is still slow. After much research, I discover that my harddrive is now the culprit. Not only is it full of 4GB games, but its seek time is slow, and the throuput is now a bottle neck. Guess I need a fast SATAII harddrive.
Creative XFi Fatality $180
SATA II HDD $100
So now i Have spent $1115.
I havent covered the cost of games, the cost of taxes and/or shipping. And I havent covered the time that was spent installing everything, updating drivers, BIOS, firmware, etc. And after all of this, in a few months, nVidia will release the new nVidia GeForce 9000GTX or something, and my 8800GTS will no longer be new. And then a new slew of games will be released, and my $1115s of upgrades will not be good enough. If that isnt enough, keep in mind that you may also have to buy a new case, or a new DVD rom, or if you are feeling wealthy, you can get a Blu-Ray or HD-DVD drive.
OR
You can spent $499 for a Playstation 3.
And start playing games the same day.
As a bonus, the PS3 comes with a blu-ray player.
For me, the choice is easy.
