I'm new here and lot of posts have helped me understand a bit about graphic cards. But I still am not sure which video card to buy.
My only intention is to play starcraft 2. I am planning to buy a new PC and then install a new video card on it to play SC2.
I looked at affordable one's like HD 4670, 4770, 4650 and nVIDIA ones like GT 240. They're around 70-80USD on ebay/newegg.
There are two other cards i've been looking at. HD 4850 (512MB or 1GB) or GTS 250 1GB card. I could get one of these two for ~120USD.
But I want to know if any of the affordable cards can play SC2 well @ good settings.
For all of the options above, the strongest card is HD4850/GTS250, u can choose which one is cheaper...
What about your plan(new computer)? Monitor?
U might want to consider HD 5750, u will be better with a newer tech.
The problem with buying a pre-build system from stores like Best Buy is that you have no idea what power supply is included in your system. Given the low-powered nature of your linked system (CoreI3), I'd bet there isn't much of a power supply in there and probably not enough to power any of the higher end cards people have suggested.
If at all possible, contact either Gateway or Best Buy and find out what power supply is included in that system before deciding which graphics card to purchase.
according to gateway, the above PC has a 300W power supply. It probably wouldn't be enough i guess and I'll need to buy a new PSU. How hard would it be to install a new PSU and a VC in a system?
yes but from beta, they say the 9800GT can run the game on very high. Since you have a 17" LCD, the ATI 5670 can run on a 300w, give similar performance to the 9800GT, and will run the game on very high with your current monitor.
The SC2 beta is showing some 'love' to the Green Team. It's showing the GT 240 edging out the HD 5570 / HD 5670 (even though in other games the HD 5670 is usually out in from). And the GT 240 draws less power than HD 5670.
oh ok, thats for 1680x1050 resolution, so it should be higher frame rates @ 1280x1024 right?
also, another question, has anyone heard about www.ibuypower.com ? i was look @ their cheaper systems and customizing it will cost me about 800USD (my max budget) inclusive of HD5750 + 700W PSU etc. is it risky to buy PC's online?
