My daughter recently bought the Sims 3 and has not been able to play the game due to not meeting min. requirements. So I want to buy a new MB / CPU, preferably AMD, that hopefully will last the next 3 yrs or so. I have been looking at boards that have the built-in Radeon HD3200 chipset (like the Gigabyte GA-MA78GM-US2H) and NVIDIA GeForce 8200 chipset (like the ECS GF8200A). I want to pair this new MB up with an Athlon 64 X2 7850 processor. Also, it would be nice if the MB built-in graphics could use up to 512 MB of the system memory (not sure if these two MB's both can do this or not). Are MB's with the Radeon HD3200 or NVIDIA GeForce 8200 chipsets a good choice or would you recommend a different chipset / MB not listed? I'm trying to keep MB / CPU cost under $150. Thanks!
