I have been having trouble lately with some Unity games that should run okay on my Mac Mini. Recently, Goggles World of Vaporia, which looked like a pretty cool little 3rd person game runs poorly--even on the lowest settings it plays, but it is really not playable, if that makes sense... I noticed after my purchase that the minimum Mac requirements included a NvidiaGeFoce GT 750M or better. Would this be a good upgrade for my Mini. My specs are:
Mac Mini Intel Core i5 with 8GB RAM running OS X 10.9.5 Mavericks, current card: AMD Radeon HD 6630M 256 MB.
Are Nvidia graphics that good for gaming, and can I get a reasonably priced one for around $200.00?
