Basically I am a complete noob at this kind of thing. Plus i'm on a tight budget all i know is this is what I've got and need to upgrade the card. just want to run basic games, mine craft age of empires II tf2 any advice would be great thanks.
Yeah, about the same CPU generation as my 740's Athlon 64 X2. I would go for a low profile 6570/7570/6670/7670. I would avoid any 'silent' cards, as Dell's stupid decision to put a large heatsink on the onboard graphics chip, which is right next to the PCI-e slot, means you have to choose a card with a slimline cooler, which sadly means most silent colling cards just wont fit, as their heatsinks are too big and hit the onboard's Dell heatsink.
