A little information: the G450 is to all intents and purposes a die shrink of the G400 (it adds nothing in particular) which however has not received drivers for Windows 3.x (while they exist for the G400 which however does not have a PCI variant).
The only possibility, with G450 under Windows 3.x, is to use the generic 256-color VGA driver (up to 800x600 if I remember correctly).
If you put on a 486 PCI build and intend to use Windows 3.x, if you choose Matrox as video card, you should prefer either Matrox Millennium/Mystique (correct or nearly correct for time) or G200; these cards are PCI version and have Windows 3.x drivers
Thank you for those precious information, did anyone try to use the g400 drivers with windows 3.1 with the 450?

I tested it in 3d (3dmark suite) and it's noticeably slower than the agp version, I found out the pci version has decreased clock speed compared to the agp, despite using nice 5ns memory, the clock seems to be tied with the core and I wasn't able to find any utility for some overclocking.
Please, do share more. Is the clock 125/125? Reported by what program?
Powerstrip reports: 115 mhz for the core and 144 for memory (288 since it's ddr).
The AGP version of G450 reports: 125 and 166.

G450 is somewhat tricky to OC due to weird multiplier thing going with core/memory ratop. But in general you can reach G400 Max level of performance. Well, not on PCI obviously, but close enough.
How so? If I overclock it just a bunch of megahertz (for both memory and core since they are tied) the card become very sloppy (no artifacts but windows become slow as hell, I have to reset the system because it ends being unresponsive).
According to the tests I did with 3dmark99 it does less than 3500 points while the agp version did more than 5000.
Fps are almost halved compared to agp version.
Some information about the card in case there are more pci versions:
Manufactured in 2007, it's a oem ibm card, the drivers need to be installed manually.
I found the bios version be the: 1.6 - 29 while the latest is 2.1 - 37
I'm still undecided if update it or not.
Memory chips are Samsung k4d26328k-uc50, there are 2 of them (16 mb each).
