I don't know of what website you're talking about. If you post and provide all the information in the "How to ask for new build advice" sticky at the top of the forum we can build you a system optimized for your intended use and budget. We could do a lot better than an automated website.

ok i have amd phenom II 965 140w,M4A7TD-V EVO and a coolmaster 460W psu whats the best gfx card that i can go for??

And that the PSU will run it, which it won't. I would highly recommend investing in a good PSU. Coolermasters are pretty much crap.

And again, we really need to know more (the case, age of the PSU, resolution of the monitor, etc). The guidelines are there for a reason.

It's likely that the best GPU you can run is the HD 5850. If that's the best choice for what you want to spend or what you're doing, we have no idea until you follow the guidelines.
