Unfortunately, neither the GT 440 (aka GT 630) nor the GT 520 (aka GT 610) is certified by Adobe. In fact, Adobe will never certify any GPU that costs less than $350 when it is introduced. Both the GT 440 and the GT 520 were introduced at less than $100 to begin with. Second, both the GT 440 and (especially) the GT 520 are weaklings that are actually slower than your system's CPU! Third, by default with a non-certified GPU you are locked into the software-only mode. In my own testing with CS5.5 on my main system with an i7-2600K that was overclocked to 4.4GHz I found the GT 240 (with 96 CUDA cores) needed all of 249 seconds in the MPEG-2 DVD test in PPBM5 compared to the 111 seconds required by the more expensive 448-core GTX 470. Worse, if your GT 440 uses the much more comonly found DDR3 VRAM instead of the harder-to-find GDDR5 VRAM, expect the performance to be even slower than my GT 240 (with GDDR5 VRAM) was.
