Hmm, that's a geforce2 MX not a geforce2.
That is definately too slow card for the system, I thought you had a geforce 2 Pro or something. You got screwed there..
Pentium4 SDRAM boards should not be sold for gaming use so yes, Dell screwed you.
Windows XP home should not be sold to anyone, you got screwed there also..
I suggest you give Dell some feedback. That sdram motherboard is going to eat a good slice away out of the potential computing speed of your P4 processor. It was designed to use RDRam with is about 4 times faster than normal sdram.
Geforce2 MX is as fast as the original geforce that came to market 2 years ago, it's outdated for 1 year now. However since aces high has low hardware demands it might give you around 60 fps, less than 20 in heavy smoke. A geforce3 Ti200 will outperform geforce2 mx in all applications by at least 3x speed (even 5-6x in Dx8 applications) and costs only about double from the mx. I'd get that one - or radeon8500 which starts to have drivers now.
Windows XP home is a mutilated version of the Pro, it has huge security flaws like IIS preinstalled, poor gaming compatability (problems with hardware like joysticks) etc etc.
Of course your first mistake was to buy an Intel board if you wanted to get a cheap computer. If you must stick with Intel, you should have bought P4 1.6+ with an RDRam motherboard, 256+ rdram, win98se for gaming although I'd suggest w2k which I use. XP at the moment will bring you more trouble than benefits, it's still too young a release.
If you have any chance to return that computer and do the changes above I'd strongly suggest that. Your Dell was not optimized for any use imaginable. For gaming it has too low-end parts. For office use it has a graphics card which is infamous for its poor 2d quality and fuzzy high-resolution picture..
So your computer is good for nothing basically. Sorry to say this but its true.
It will probably beat your old computer in terms of performance, but I can assure you that the computer I built myself from VIA parts, geforce3 ti200, ddr ram etc.. will outperform your new computer with similar price here and back. Another consumer has got Dell'd it seems.
Oh, and if you're going to stick with the XP home you need to download, install and run
this if you want to have more than 60hz refresh rate in games (trust me, you do.)
Run it with the option 'set all resolutions to 85hz or closest' and then check that your desktop is set to 85hz refresh.
With a geforce2 mx I don't suggest using anything over 1024x768x32 resolutions, it's picture gets fuzzy at higher resolutions.
