I need help choosing a graphics, i am building a new computer and didn't know which graphic card would be the best
I am choosing between the 4770 and 4670, and i am comparing them to a 9600,
My questions are:
which one is better than the 9600?
What is the difference between the two and how much of a difference it would make in real games?
I play games like COD4 and downloadable games for my parents
Radeon HD 4770 is better because it is the fastest between them and it is a DX 10.1 video card while Geforce 9600 is the older generation DX 10 card from NVIDIA (refreshed of Geforce 8800 series but NVIDIA rebranded them as Geforce 9 series).
However, if you were to get Radeon HD 4770 to play COD4, it would actually be better if you spend a little bit more and get the newest and latest DX 11 generation video card like Radeon HD 5770 or at least Radeon HD 5750 or if you have more budget to burn and play at higher resolution then you could go with Radeon HD 5850/ HD 5870. Most people would still recommend Radeon HD 5770 over Radeon HD 5750 but HD 5750 is good for those on a budget and it will outperform HD 4770 and allow you to see DX 11 quality graphics or allowing you to play future DX 11 games (in DX 11 mode). That is just my recommendation but if you wanna stick to the cheaper, older generation video cards then that's fine.
so the 4830 is a weaker graphics card than the 4770?
All generations have cheaper cards and more expensive cards so there will be cheaper HD 5xxx cards (Radeon HD 5600 series' price would be around your budget) but the only problem is that you had to wait. Companies look at many different customers with different budget for spending so this is why they make cards of same generation but at different performance and at different price.
Anyway, if you must buy now and don't wanna go with HD 5700 series which are the current cheapest HD 5xxx cards for the moment then most people would recommend you Radeon HD 4770 especially if you wanna do gaming and spending less. Try not to go below HD 4770 for gaming otherwise you will lose a lot of fps for real action games like COD4. Since you are playing real action game then you need a more powerful card like at least HD 4770.
I think that HD 4830 is slightly weaker than HD 4770. HD 4770 uses 40nm GPU and HD 4830 uses 55nm GPU so HD 4770 will produce lesser heat than HD 4830 and allows you to overclock more as well as consuming lesser power than HD 4830. HD 4770 would even save your money more than HD 4830.
Between HD4770 and HD4850 you should just pick the best price because of little performance difference. Keep in mind though that the HD4830 is almost as good a card and it is up to you to decide how much cheaper it needs to be to warrant purchasing it. Take a look at the link I posted before in this thread and maybe it will help you decide.
