Radeon HD 3650 vs 7900gs which is better?

[xacegamer15x]

I found PC parts and put together a PC with an amd athlon 64 2800+
I like building PCs I built my own not long ago with a gtx 1080 ti and i7 8700k
For this I found the HD 3650 and the 7900gs there are many more like the ati 9550 9250 and the s3 but my father says these 2 are the most capable

Since I haven't used many PCs before I have very little idea about how they compare and my father doesn't remember either

Could you tell me how they compare with each other and with the 1080 ti?
My father says they are old so should be used for old games but I haven't really played any game that came out before 2009 except crysis

The 3650 is a lot stronger , maybe 50%, than that 7900gs.

Oh that sound really good but it wouldn't give any screen :/
Same everything the 7900gs gave screen just a moment ago shame

Thanks for the help

Shouldn't matter with that CPU and I bet that rig only has 1-2gb ram at max

the hd 3650 supports dx 10.1 while the 7900gs only supports 9c but since you have an other computer that supports dx12 and can play every game max settings it shouldn't really matter where the line is when you need to turn on the more powerful rig
