I was wanting to get a new grapichs card and im not to familar with this at all. Was wanting to get a new graphicsa card but i didn't know which one to get based on the power supply, if i have enough power for it it'd like to get the Nvidia GTX 460. But if i dont' i would get the Radeon HD5770. I can't upgarde my PSU so whatever is their and Whatever i can run on the PSU i currently have.
I was leaning tward the GTX because of how many bits more it has than the 5770 but i have no idea what i'm doing, so any help would be apreciated.I'm not an Extreme Gamer but i like to play all the lastest titles as much as i can, and i dont do anything on my comp but play games and surf the internet.
I Can't get a better PSU cause i can't install it so i'm trying to get the best i can run on the one i have.
The 460 GTX 1GB FTW that you listed is a very good card, but if you want to spend less and still play all the latest games at high resolution you should go for the ATI 6850. (Same price as the 5770 you listed, but much better performance). And if you ever feel like overclocking, the 6850 is a very good overclocker.
And just on the off-case your power supply is not enough (it might be a low quality power supply..I'm not an expert so I don't pretend to know more than I do. . but better safe than sorry), the 6850 does consume much less than the 460. I believe it's max consumption is around 130 versus the 180 max for that 460 GTX FTW.
Bottom-line, if you want to go for the cheaper solution that is still a very good card and will run everything smoothly on ur resolution, or you don't feel like taking power requirements risks, get the 6850.
Otherwise, get the 460 GTX FTW 1GB (It's a very good overclocked card and I think at this price-point it cannot be beat performance wise)
PS: I am also ordering a 6850 at this time of writing because I also own a no-name 500W PSU (18A@12v1, 18A@12v2) so since it powered my 4850 fine, I went for the 6850. Didn't want to try to get anything higher in terms of power consumption in case it doesn't work.
Thank you for that, was helpful but i'm still having a problem knowing if my PSU can handle the 6850. I saw it today at newegg but i didnt look into it because it says a minimum of 500 watt.I was looking for a 450watt one cause i wanted to be safe when im overcloking my CPU and GPU.But i am still unsure of what exactly the power requirements are and how all that stuff works.When i looked into some of them they say at least 24Amps on the 12/v rail and i have 34 i think is that good? If someone could clear that up for me! Thankyou
For performance wise as in better FPS what would be better out of the 3
An entire system with an HD 6850 consumes about 230-270 watts under full load.
As for your PSU, you more than likely do not have 34 amps on the 12v rails and your screenshot does not give a clear answer. But even if it's not 34 amps, it should be around 25-30 amps, which is still fine for any of the cards you listed.
