now again m confused ? now hd 6850 is not good for me neither do 5770 ? then what should i do ?
NO NO NO! You are on the wrong track buddy..... The hd6850 is better than the hd5670, but at your resolution, you don't need a great card, that is why he suggested the hd5670. You want to be future-proof and play games maxed out, right? It is not about a better card being worse, some cards are just better, but you do not need all that power. In this case, you do not need more than a hd5770,
FOR NOW! Later, when DX11 games (which the hd5xxx series suck with) you will be more future-proof with the hd6850. I suggest the hd6850 knowing that you will not be disappointed at all. Apparently you do not know that some cards are just plain better than others, period. At least, that is what it sounds like. The hd6850 blows the hd5670, and the hd5770 away, in like any game. That means that it is a better GPU. right now, a hd5770 would be fine for you, but later, you will need more power like a hd6850.
GET AN AMD HD6850, AMD ATHLON II X4 3.0GHZ, AND 4GB 800MHZ RAM! After that, you will be set, despite people saying you don't need it, you will,
LATER. Tell me what you think.
