I have a Dell Inspiron 620 MT desktop which comes with a 6450 card which I am about to get rid of and get a newer 6670 card.
The system is only 2 months old.

Spec:

i5 2310
6 GB ddr3 1333 mhz ram
1.5 TB HHD
not sure what is MOBO model
300 W PSU

Do you think this card will fit into my case ?( I am not sure how long and wide this card is ) and will a 300W PSU handle this card will?

and what is the different between a ddr3 and a ddr5 version. price is only 30 bucks in difference

OK, this time I added some open case pics, a pic of the psu and a pic of the size of the case with ruler...
Now, Can someone please confirm if the 6870 could fit in to the case and the psu will be good

I dont think 300w psu will be able to feed the gpu 300w is just too low the requirments of this card is well over 400w

300 Watts should be fine.
Typical system with a 6670: Idle under 100 Watts, When loaded, under 200 Watts.
So 300 watt PSU would only be loaded to 66%.

The requirement "400 Watts psu" is to allow for Lousy PSUs that can only deliever about half the rated power. That said I have no idea of the quality of the Dell PSU, but should be OK.

Size wise, need to measure inside your case and find the dimentions for the card.

With a TDP of only 66 Watts, I think that 6670 will easily be handled by your PSU. And if I were you, I would get the GDDR5 version.

It's about 35 bucks more, but what's the difference?

Just look at the picture ; It's just a bit longer than the pcie slot as you can see and wide as the slot on the back of your case and it takes the room of two slots.
Dell psu is good quality and you'll be able to run the 6670 with it.

Newegg has a calculator for this question. It is easy to use although it not as precise as some of the more complicated calculators. The 6670 will be fine on a 300 watt PSU just don't step up to the 67__ cards as your pushing your luck on powering them if you do.

More memory bandwidth of GDDR5 = better performance than DDR3 ( but not THAT much )
The GDDR5 6670 will be the most optimal card to get if you're stuck with that PSU.
Or perhaps, you may wait for the HD 7xxx series coming soon, which is on 28nm technology which will allow better performance at the same power consumption.

If you really want to be sure, you should be able to remove the PSU from the case and see a label that says how much power it will put out at what Voltages. That is probably more important than if it is a 300W PSU.

Exactly. Dell uses minimum-sized PSUs, but they aren't crap; in fact yours is probably 80+ or even 80+ bronze.

The PSU is one of the older ones that doesn't have Active PFC, but with 18A on the combined +12V rails it should have no problem with a HD6670. I am assuming that "6870" under your pic was a typo; you will NOT be able to run one of those!
