Playing SSE2 games on SSE1 CPU

I have an old computer using athlon xp, ddr1 and agp which i planning on upgrading its graphic card from radeon 9550 to hd 2600xt. i did some googling and found out that new games (GRID, DMC4, CMR Dirt) abandoned sse1 support and use sse2 which unfortunately athlon xp doesnt have. so, i want to know is it possible to get sse2 games running with my athlon xp? i want to know whether or not buying a new graphic will be worth it, if it is not possible i am going to stick with 9550.
i read on a forum, the game .exe can be change from sse2 to sse1 in 10 minutes but i dont have any knowledge about how to do it or anything on programming. any of you programmers here know how to do it?

does it require SSE2?
if no then you’ll be fine
if it does then no.
Answer #2
as far as I know only one method. If you can found SSE2 implantation in SSE1. Than use it. But this kind of software reduce CPU “because they neeed CPU” If this kind of enulation or implamataion exzist you can use it. But I don’t know. If you good at ASM maybe you write it. But I think you should search. For example Directx 10 -> windows Xp ” some group writed and working ”
Answer #3
i did a search on sse2 emulation, i couldnt find a software to do it but i read somewhere that emulation will cause to much slowdown that it will be not worth it.
