I think I got a Pentium 770, maybe a 780 on my T43p… it is nothing compared to a T61 T2500.
But then again, if you want that system with IPS without mods and all that fuss fuxx…. Yeah its fucking sweet! Honestly it was bittersweet seein gthat X300 screen against the T43p, but that was in 2014, idk how either system will fare now in 2025.
