If the 610 is just an intermediate card, and your current GPU on the motherboard just isn't enough performance, then go ahead. Don't bother spending more if you plan on getting a much better one soon anyways.
I've checked a few youtube videos of people playing minecraft with the 610 and they say they can get perfectly acceptable frames.
I play with Minecraft with a RadeonHD4200 (much worse than a 610), and I get playable frames. It doesn't compare to my desktop at home, but for an intermediate solution, there are no issues.
Are these any good for my purpose? Does anyone know of any better ones for cheap?
BTW my specs are (don't laugh):
Manufacturer/Model: Packard Bell IMEDIA B2316 AIO
Processor: Intel Pentium Dual CPU E2200 @ 2.20 GHz 2203 Mhz 2 cores
OS: Windows Vista Home Premium (Service Pack 2) (32-bit)
Thanks in advance
Nobody is going to laugh at you man but to be honest i don't play either those games so i am not sure what would be a good choice.Personally for gaming of any sort i never would recommend anything less then a 6670/7750.
