The GeForce4 MX 460 will beat the GTS easily.
128Bit DDR 300/275 Clock, and the GPU overclocks like hell often.

I had one.. and it even run HL2 well.

I was looking over old 4MX reviews and while it looks excellent with Quake engine games, Direct3D stuff was not as glowing. With D3D games the GF2 Ti was beating the MX440 handily in some games. I don't know if there is some more thorough testing to look at out there that gives a more complete picture.

Perhaps the Quake engines are especially friendly to the occlusion culling tech and other improvements. I know first-hand that GF3 runs Daikatana (Quake 2 engine) much better than GF2 Pro at 1600x1200. If a game doesn't benefit from the GF3/4 efficiency improvements then the 4MX would likely fall behind because as has been said the GF2 GTS/PRO/Ti/Ultra definitely has the raw fillrate advantage.

I'm working on a big GPU benchmarking project... for many years 🤣 It is not ready to be published yet, but I can post some numbers when I get home.

GF2 GTS, GF2 Ultra, GF4 MX 440 (64-bit), GF4 MX 460 and many others are already finished. Aside from Q3A (which everyone is testing 😀 ) I have in my methodology plenty of other games - but mostly newer because DX7 HW is just a starting point for me and the top end is set to GF 7800 GT, Radeon X1800 XL. Anyway - from the less demanding games I can pick for example GTA Vice City, RTCW, Max Payne 2, Serious Sam SE, NFS Underground or HL2 in DX7 mode.

Ok, here it is.

GeForce2 GTS - 200/333 MHz, 32 MB, 128-bit
GeForce2 Ultra - 250/460 MHz, 64 MB, 128-bit
GeForce4 MX 440 SE - 250/266 MHz, 64 MB, 64-bit
GeForce4 MX 460 - 300/550 MHz, 64 MB, 128-bit
GeForce3 Ti200 - 175/400 MHz, 64 MB, 128-bit

Pentium E5700 @ 3.9 GHz
2 GB DDR2 600 4-4-4-12

MX460 doing well there!

Yep, it really does very well in these tests!

And there are different 440's out there, I wonder how this one would score:

Prolink PixelView GeForce4 MX440-8X Videocard Review
http://www.pcstats.com/articleview.cfm?articleID=1241

[quote]
Prolink is targeting the gamer on a budget with the PixelView GeForce4 MX440-8X because
the card is probably one of the fastest GeForce4 MX's out there. Prolink clocks the core of
their card at a full 300 MHz up from the 270 MHz most other MX440/MX440-8X's are clocked at.
The memory is clocked at an amazing 550 MHz, again up from the usual 400 MHz of most other
MX440 / MX440-8X's.

For all intents and purposes that should perform identically to the MX 460.

It really depends on the type of Geforce 4 MX that's being benchmarked. There are TONS of varieties with many lower clocked or lower memory bus versions out there. A proper 128 bit MX440 with 400MHz memory should be faster than a Geforce 2 GTS, while an MX460 is a beast of a DX7 card. 😀
However, most MX440s are 64 bit versions or ones with the full 128 bit bus with a 333MHz frequency for example. There are many dud MX460s too, so you really need to be sure what you're getting.

Regarding the MX4000, they were a low cost alternative in the FX times (hence the 4 digit naming scheme) with a 64 bit memory bus for 128MB ones or even 32 bit in some cases with 64MB on them. The latter is roughly equal to a slower Geforce 2 MX 400 if the memory runs at 400MHz. 😵
They then went further with these and made the PCX4300, the only DX7 card for PCI-E (with a bridge chip of course). 🤣

Basicly, MX420 = MX400 MX440 = Geforce2 Pro/TI and MX460 = Geforce2 Ultra.

And there where times an MX440 would beat an Ultra. Remember the Geforce2 doesn't have Z occlusion and does not have a crossbar memory controller, so its fillrate means very little, you could crank a Geforce2 Pro to Ultra core speeds and see almost no gain, while if you turned the memory up 10% you got a 10% FPS boost. The Geforce4 has the Geforce3 Crossbar memory controller and Z occlusion, meaning with it you acutally saw a gain with faster core speeds while leaving memory alone.

To the OP: look for a Quadro2 Pro also. It's the workstation equivalent of the GF2GTS. I have one and it performs indistinguishably from the true GTS. One tip for searching on sites like ebay, etc: often you will see cards listed only as "video card" or "nvidia card" without specifying the model - often the seller doesn't even know what they're selling. Be prepared to identify the card visually by comparing with pictures of known card models. Often you will see FCC ID numbers, manufacturer P/N and so on in the auction pictures; google those. Yes that takes a bit of time but can be rewarding. I bought the Quadro2 Pro mentioned above this way from an auction with the title "nvidia card" for $10.
