bcknee :
I have gotten the sims 3 to play relatively smooth on a single core processor so I don't think it requires a six core, I agree with mostly everyone else to buy a quad and get a better Video Card.
Yea with medium settings? anything above that i think it would struggle.
Seriously things can get pretty hairy if you turn the AA up at low resolutions even with a dual core.
So if you wanted anything but mid-low settings then a single core isn't really adequete.
ime it will play MID-LOW settings on a rig with slightly under the minimum requirements at about 30-55fps which
imo is no fun :|
The reason the resolution of the moniter he intends to game on is important, is that while a 5770 would be ideal for about 1366x768, it would stuggle with, for example, full HD on full settings in this game; If i was building a rig to specifically play a game.. i'd want to play it at full settings and a fluid 60fps
For this reason if the moniter is above the stated resolution i would suggest a Phenom II x4 @3.2 paired with perhaps a GTX460
While the suggested graphics card is slightly over your original budget, the CPU i have suggested is just fine and pretty much makes up the difference
just 2kb tho
disclaimer;
several patches have been released since i last played this game... some or all of this information may not be valid.. i am not responsible if your computer explodes / combusts / becomes sentient and enslaves humanity, etc, etc.
