I would probably stay away from the GF4 MX 440 or 420 and I would expect that the GF2 TI or GF2 Pro should close in speed. The only thing is that the GF2 will not have the new LMA II or the new DVD hardware assist that the GF4 MX has, plus don't forget Nview to let you view two monitors/tvs at once. The GF2 Ultra would trash it in most tests, but anything under that will be close to par with the GF4 MX 440. Any GF3 will wipe out the board when comparing the Gf4 MX. If you are into gaming and want a good card with not alot of price, go with a Gf3 Ti200 or a Radeon 8500 and you will have good value for price, but if you do a bit of everything, you might want a Gf4 MX440/460, I would totally stay away from the MX420.
