what gpu to buy for a pentium d 3.40

Go the 660ti. Nvidia gpu's come in generations, ie 600 series 700 series etc, the higher the number in that series will be the best performer. A 710 is the worst from the 700 series, a 790 the greatest, you want the higher last two digits of any series you choose which is why i chose the 660ti above those 700 series low enders. I would also replace the psu with a voltage of 550w at least

rgd1101, seriously man, why close the OLDER thread? That pisses me off... I already replied with a pretty long post and it was closed, throwing away that reply in the process

As for the post, here's the gist:

It's a crapshoot, most likely it will NOT work. Even if it does, you'll be CPU limited in modern games and non-accelerated video will stutter

And unless he needs it for a server, your nephew will say "thanks" then throw that thing in the trash because it's too slow and old

That computer is so old and so weak compared to any modern computer.
It can't even handle modern flash based web.

I suggest you think abouut replacing it all not just the GPU.

What the hell are you talking about? The link I gave you was for one with a MUCH,MUCH,MUCH faster GTX 950, a high end PSU, and 8gb ram!

I suggest the mobo here its a gigabyte with intel chipset, Intel is better and durable in terms of high gaming performance and high temperature, click here: http://pcpartpicker.com/part/gigabyte-motherboard-gah110ma

I already mentioned that motherboard in the link above, as it's one of the cheapest skylake boards

Ok sorry, we have a same specs I like also, but I promote you offered to here.

That PC I linked is good enough to play any modern game at 1080p, though not at the highest graphics settings. For any games from before 2012, you can certainly max out settings and get >60fps.

For the pentium d? I highly suggest not bothering to put any more money into a system that old, though at least the PSU can be carried over. Just not that PSU, that's a PoS that should NEVER be used with modern equipment.

Again, a GPU is pointless to even consider until you check your firmware for compatibility!

Don't do that unless you want to burn out your hardware... Get a real PSU, it's cheaper in the long run

They are mobo/gpu burners, rubbish bin fillers, door stoppers.

Go Tier 1/2 or maybe 3

Tier One
The highest quality and most stable Power Supply Units available. Protected by industrial grade protection circuitry and can output wattage at a rated maximum temperature of 50°C or below. These units are also Haswell certified, meaning they can cope with the C6 and C7 sleep states of 0.05Amps without triggering the under-current protection switch. May even go over labelled wattage and still work until it safely shuts down.

Tier Three

Some Haswell compatible, some not (maybe unconfirmed). Still safe to use and stable, just lower quality components. Not really ideal in serious overclocking or super-high load situations, such as a Bitcoin mining rig or a high end gaming system.

very bad idea, most of their stuff is not even ranked!

evga or corsair are safer, and seasonic is always good (even their worst is above average)
