I am yet to test out the game as waiting for a guest pass from my friends,i am pretty sure will need to upgrade components as my computer is outdated thats what i wanted to try it first before i bought it as on a tight budget.
i want to be able to run diablo 3 at its best here is my spec.
windows 7 professional x64
AMD phenom 9550 quad core processor 2200mhz
4 gig of ddr 2 memory
ati radeon hd 3650 512mb memory
i am pretty sure my video card needs replaceing right away cause its no good period.But like i said i am on a tight budget and no good at these things as not upgraged for ages as had no need to cause not played a game on the pc in an age,been waiting for diablo 3 to be released.Been looking at a :
As much as know about graphic cards that one might be weaker than yours. First digit is generation, then class (like performance-value-budget etc), then next digit is also related to how powerful it is. For eg. I have a 6770 and they say it's pretty much same as 4770 just newer (so it can do directx 11 which is not really performance related anyway, i'm not sure where it matters really).
If I were you I'd get a x770 or x850 I think.
I upgraded recently to an i5 cpu as well, but the game seems to have performance problems lagging sometimes, as far as i can see it should not lag on my pc at all. It's d3 not an mmo with super graphics and 100 people around.
If it works on lower settings you may as well wait with the upgrade unless money burns your pockets.
I guess your computer will rune D3 fine. I don't know about your gfx card, but I think it's better than my Geforce 9800GT and it runs smoothly at 1920x1200*, except I fiddle around with the gfx settings.
* The game itself probably works at a lower resolution, so I guess it's just scaled up to that size, which probably doesn't stress the gfx card.
