Assuming you don't go for an external graphics card which there was an article about over on Arstechnica.com last year, yes a desktop is likely a better solution. Additionally, I would suggest that you build it yourself so you aren't saddled with a low PSU or other issues that can happen if you order a system on-line and later find out that this won't work down the road as well as you thought.
If you go to sites like Extremetech.com's Build It section they have examples of a gaming machine you could build yourself if you are so inclined. Newegg.com is often mentioned as a site where you could order the parts, fwiw.
A few things to ponder in the new system is whether or not you want to get Vista in it or not. Similarly, do you want to get a DX 10 card now or later to support the latest Direct X that games in the near future will likely take use like Crysis for example.
Just a suggestion,
Ok...so I recently graduated college and throughout the duration of my college life I had a Dell Inspiron 8200 which I got in 2003. Just recently my backlight went out and I am going to fix it but I realized that this is just a bandaid on a larger problem. I love to play games. I played CS and CS source as well several other older games but I cant play any of the newer games like WoW (which I found i love to play on a friends new computer) and FPS like FEAR and Doom 3.
So this leaves me in the market for a new laptop. I have been reading the forums and researching cnet as well as building dream laptops and desktops on manufacturers websites (IE Dell, HP, etc..) and came to one conclusion. Is it even feasible to find a laptop that can last me a while? (at least 3-4 years) Without getting phased out by the massive demands of new games? Is it even possible to find a premier gameing laptop below 2200$?
I love the mobility of laptops, but they are inherently doomed to fail due to Moores law and whatnot. WOuld an upgradeable desktop be better? Either way what companies are best known for quality support without crucifying you with expensive extended warranties?
I understand this is getting long so I came to the following conclusions:
1 The minimum amount of RAM I would want is 2gigs.
2 The core 2 Duo processor and Athlons equivalent are pretty much the indusrty standard ATM
3 SOme companies are not even packaging a Video card or Grahpics processor or even physics renderer due to processing efficiency ( is that right?)
Ok I probrably left out the bulk of what I wanted to say due to rambling but any opinioins on systems and companies would be greatly appreciated.
