I don't know which Video card shold I choose, I'm between the HD 5670 and the HD 5750. I have a C2D E7500 (2.93 ghz), a mobo that only supports PCIe 1.0 and a monitor whose maximum resolution is 1360x768. I don't know if buying a 5750 worth it because of the PCIe 2.0.
If I buy the 5750 I'll need to buy a power supply (U$S 70) becouse the one I own is generic. Also, taking into account that I live in Argentina, the prices are different, a 5750 costs U$S180 (very cheap) and a 5670 U$S149 (very cheap too). And one dollar is four pesos.
I'd like to play games in 1360x768 in high, so, what would you recomend me?
If your PSU has a 6-pin connector, then you can get even a 5770 and run it with no problems at all. If you don't have a connector - go for the 5670.
By the way, is your PCIe 1.0 @16? Almost all PCIe products are compatible with each other.
well, either card doesnt really use that much power. Can you be more specific with the brand and model and specs of the PSU you have, not all generic PSU's are completely useless. But I generally would not reccommend generic PSU's for any gaming PC.
