I myself have a degree in that field and with regard to most gamers in the middle-computing power, middle-cost class an upgrade in processor is usually better than in video card. Why you ask, because doom 3 is a processor and video card intensive game. The minimum requirements of 1.5Ghz processor tell you this right on the box. Sure you need a good video card too but even if you spend $500 on the latest greatest card it can't perform without a processor and bus capable of feeding it. If you have near 3ghz processor then upgrade in video card will do wonders but if you have around a 1.5 ghz processor and buy an expensive ass video card your not going to see the performance you paid for and would have gotten better performance for cheaper with a processor upgrade.

Most CS degrees don't teach you about extremely detailed hardware information. I DO know this information because I read very intricate, in-depth reviews and analyses on the Internet from trustworthy sources every single day. It's a fact that the videocard handles most of the computations within games nowadays. If you're faced with upgrading to a midrange videocard or a midrange processor, it's still best to go with the videocard. The days of a processor upgrade being better than a videocard upgrade are over. If you have a crappy videocard and a crappy processor, it's better to upgrade all of it, but if you have to choose, a videocard will benefit you three times over than a new processor.
Doom 3 can barely be called a processor intensive game. If a $50 processor and a $400 videocard will run Doom 3 VERY well, then the videocard is obviously the main factor. Like I said before, there's a small increase in performance within Doom 3 even from a huge processor upgrade. There is a MASSIVE increase in performance from upgrading to a better videocard. The game is RAM (amount, not speed) and videocard intensive...barely processor intensive (even though you need a somewhat decent processor to play it).

I hate to be an ass, but that's not right. You'll see a much larger performance boost with a 1.5 GHz processor and a top of the line videocard than with a better processor and not top of the line videocard. Like I said before, gaming performance with, say, a GeForce 6800 Ultra and a $50 Athlon XP 2000+ will totally outperform a 3 GHz Pentium 4 with a GeForce 4. There's no getting around the tests!
