i currently have a a6-3620 with a radeon 6670 in my pc, it runs greta no problems, but a freind is willing to sell me a spare radeon 7750 he has so i am curious if ill will get even better performance without dual graphics mode and the newer architecture card, i play at 1280x1025 so these cards are pretty powerful for my needs already but i am looking mostly to just play war thunder maxed out and a few other titles like modern warfare 3, some world of warcraft and such, nothing super graphically demanding at my res, but so yeah thats the situation will i get better performance with this radeon 7750 without my dual graphics capability i have now?
