Or you could always get a mx440 64meg ddr card for like 50$ new, and like 38$ refurbed at newegg. I think the mx440 will last you a good year from now (look at sig, bros comp uses), he plays battlefield 1942 just fine at 1024x768x32 with max details ~58fps average.
also ut2k3 runs fine at 1024x768x32 medium settings, dunno about doom 3 though, that will most likely kill a mx440, and cripple a 8500le for that matter. But that wont be out for like another 2 years, and for 40-50$ you can get a card to hold you off for a good year.
8500le is like 75$ with reg ram, not bga, which tends to not o/c as well. This card will give better preformance, and last 3-6 months longer then the mx440.
I would go with the 8500le to hold me off, but if money is a deciding factor a refurbed mx440 would be sweet for the extreme budget.
