Guru3D has various performance charts as well, and they include comparison numbers for 2 9600GTs in SLI and 2 HD3870X2s in CrossFire-X.
http://www.guru3d.com/index.php?page=vga_charts
I noticed in STALKER that CrossfireX 3870X2 results were absent (perhaps it wouldn't work?) and the 9600GT SLI result was missing from the first test in the same game. Not sure what went on. Frontlines: Fuel of War also omitted many of the configurations. The 8800GS was not included in any test. (I don't view this as a good value, what with the 9600 GT's price being only slightly higher.) Single-card Crossfire solutions from ATI/AMD were not used in the tests, either. I guess they thought 2 3870X2s were good enough.
Quick note if you're too lazy to look at all of the tests; F.E.A.R. and G.R.A.W. were the only 2 games in which 2 HD3870X2s in CrossFire-X beat out the 9600 GT SLI setup. This may change once drivers mature, however 9600 drivers need to mature as well so the performance gap may not close by much, if at all. I've never seen such impressive SLI scaling from mid-range cards with new drivers. Naturally, the 8800 GTX/Ultra SLI configurations stayed at the top of the charts in the tests (except in S.T.A.L.K.E.R. where only 2 8800 GTs in SLI were tested as nVidia's multi-GPU benchmark with no multi-card ATI configs, and in that test a single HD3870X2 took the top spot where I expected). Next move, ATI/AMD?

What are the hardware restrictions with purchasing these cards? Is not having a sufficient power supply the only stumbling block I could run into, if I wanted to get a new one?
I don't have a very powerful system and the card I'm currently using is an ATI Xpress 200. I usually get about ~30fps, or ~35 if I turn down the details.

| Well you also want to check out your agp slot, whether its 4x or 8x IMO. When I was trying to bump frames a couple years ago, I bought an 8x card, put it into 4x slot and while it did help a little, the boost wasn't what I was expecting from the benchmarks I looked at. Didn't even really know about it before I bought, but learned about it after digging into why I didn't get what I expected. |

| The only restrictions for these cards would be you have to have a motherboard that supports PCI Express. As for a power supply as long as you are over 400 Watts you should be fine. |

| Ven does your mobo have an agp slot or pci express? Also, what is your processor and ram? Sorry if I missed those in another post somewhere. |

ATI's Xpress 200 chipset uses PCI-e (the chipset itself has integrated graphics, which is what he is using, meaning he definitely has a free PCI-e x16 slot for better graphics). The matter, as he said, is if his PSU can run new cards.
How many watts can your PSU put out? How many 12V rails does it have and how many amperes is each rail putting out? These are both critical to know if you're going for a new card. If you don't know these, simply pop off the side panel of the case and look at the large sticker on the side of the PSU, it'll tell you everything. Look for what's circled here;
