That's too much processor and not enough video card. Gaming on anything less than a 6670 will disappoint you, but you could easily drop the processor down to X4 or even Athlon II X3 or X4 or wait a little bit for the desktop Llano series if you're on a tight budget.

If you want a computer that will run everything on max settings don't get it from Dell. Check out cyberpowerpc.com or ibuypower.com and be prepared to spend more than $850 on it.

a 6450 is an entry level card. it wont run games very well, but was never really designed to. you'd be better off getting the cheaper card (which is better then a 6450 in the first place, just casue its a lower number doesnt mean its slower, a 4870 will run circles around both those cards) and replacing it (along with the power supple most likely) with something better

heck no. 6670 is good enough. make sure you get a brand name power supply.
