I'll buy it nonetheless, the DX33 is lacking in my collection. What is the safest way to fix this? Align a ruler and push the pins up until they are semi- straight, then shove into a Socket 3?
Thanks to everyone who helped me out with ideas on how to fix this; a combination of metal ruler, pincets and mechanical pencils has brought the chip to this state (Leftmost row):

It doesn't look as pretty as I would have liked but it goes into sockets without issue, and should probably work.
I noticed the MSI stamp while taking this photo.. My first PC (that was exclusively mine) was a DX33 tower by MSI (who produced OEM PCs at the time, Under the Microstar International brand..), so this is a pretty nostalgic CPU for me. It's not the one I originally owned (traded it away when buying a DX4 later) but I can now build my original PC; DX33 with VLB Cirrus Logic 5428, 4MB RAM and 213MB HDD (256MB CF will have to do). Fun times.
I can now compare i486 SX33/DX33/DX2-66 vs UMC U5SX-33/40. This should be a fun project. I will probably leave it as a U5SX-40 in the end though, I feel it's a very sweet CPU for DOS games, it that handles speed things like U7 Pt1 perfectly while still being adequately fast for games like Doom 😀
I also received a Winfast A250 Ultra (GeForce 4 Ti4600) in the mail today, seller claimed it was working when removed but visual inspection reveals one major component is missing at L803/R1102/R1103 marked below:

I can make out that it reads 1R0, same as the component below but it is an unknown component type to me. What is this? What rating? I want to source and solder it on before trying the card.
