Ah, thanks to both of you, that .pdf file is great.
I'm very blank on this kinda stuff so... Modern cards are PCI-E cards, right? I'm looking at a GeForce GTX 460, it looks somewhat cheap but still good, from what little knowledge I have about this stuff. So, areGeForce GTXs PCI-E cards?
Yes, the GTX 460 is a PCI-E 2.0 x16 card...it'll work fine with your board. Just make sure your power supply is adequate enough for the upgrade and also make sure your processor isn't slooooow.
Ah, and now the question shifts to whether or not I'm willing to upgrade my processor in the future. I'm aware that my processor is also a bit old and obsolete. Honestly, my motherboard probably is too (the XPS 700 had a problem where the mobo was not compatible with more recent processors. They did upgrade them for free, but I never did it- however, I did get it swapped out as part of a repair, and I don't know if they gave me the new one).
Right now, I'm graduating from college and it's also my birthday soon, so I have a little money to throw around. My computer can only handle DX9, and I want that to change. But once I get a little more money in the bank after this, the processor is the next thing my upgrade spree will target (if my motherboard has to be eliminated as collateral damage, all the better- I want PCI-E 2 and DDR3+ support).
Motherboards continue to be proprietary with Dell's cases...either it's a Dell compatible mobo or a new case or both (meaning new PC almost). Now if you have the original XPS 700 mobo, it will support up to a Core 2 Quad QX6800 with latest BIOS. The Q6600 and Q6700 are options, but these are older quads and are considered quite expensive these days if you were to buy them new. I'd shop for a used Q6600 or Q6700 if you're in this boat....might get lucky at the for sale forums at overclock.net. I believe this board allows overclocking too and the Q6600 can overclock quite a bit
If you have the XPS 720 board (the upgrade one that you missed), that board supports the Wolfdale Core 2 Duos and a few of the Yorkfield Quads as well up to a Q9550 I think. This board would be more desirable as the Wolfdale and Yorkfield CPUs are still quite powerful.
Not entirely sure the model number breakdown between the two boards, but you can run CPU-Z and see what model number comes up in the Mainboard tab:

I'm looking for a 1080p monitor that features a nice stand that can easily be rotated for viewing in portrait mode. Seems like an uncommon feature reserved for high-end screens, as all I know of are Dell's UltraSharp line, and the U2211H at $230 is a bit out of my price range right now.
Budget tops out at around $180, 22" or larger would be nice. If there's nothing in that price range, perhaps a third-party stand that offers what I need?
Nothing worth mentioning in that price range, but this might be handy:
