Will this match?

[Dietzen]

I've got the following motherboard:

My power supply is 650w (at least this is what's said on the side of it)

I would like to purchase the following gfx card to upgrade my increasingly ancient gfx, to this:

Will this card fit into my motherboard?

Yes, it will. PCIe is backwards compatible and 650W PSU will be enough for 7870.

Look.... you need to upgrade basically your entire system before the 7870 wouldn't be bottlenecked. Don't buy it. It would be a waste of money.

 

[Dietzen]

Oh okay, good thing I asked, could you perhaps recommend a gfx upgrade that would work in my comp?
Atm I have a radeon HD 4870.

I'm running windows 7, 32bit. Running 4gb ram.

I wouldn't go over a 7770, maybe a 7750 or 6670.

Which of these would be best as an upgrade? There are so many kinds of 7770 that my head blows up

Although the menu's are in danish, the gist of it I guess you can figure out.

I can't figure out whether to go for the best mhz, ghz and amount of ram, so I'm kinda lost here

 

[Norlag]

Do you plan to overclock? If so get a stock clock 7770 (1GHz or 1000MHz). If not, get a factory overlocked card (the powercolor looks like the best deal.) A 7770 will not use 2 gb of vram, so get one with 1 gb.

 

[Dietzen]

No, I've got no idea how to OC, I've only ever tried once and it screwed up my computer.
I checked the powercooler reviews though (as this was a favorite) and it seems it is prone to artifact errors.. 🙁
I'm considering: Sapphire VAPOR-X HD 7770 OC (1 GB), since it is already OC'ed and will net me a bit more bang for the buck (and also having good reviews).

Could this seem as a good card to go with?

 

[Norlag]

That's a great choice.

 

[Dietzen]

Thanks Norlag for the help, it is much appreciated.
One last question, and it is probably the most stupid, but here goes. The Sapphire card, does it support direct x 11?
While many other cards mention this in their specifications, the sapphire card only briefly mentions direct x11 as follows:
"Crank the settings, devastate your enemies and bear witness to absurdly high frame rates with AMD Radeon HD7000 series graphics card-DirectX 11 has never looked this good."

But if it indeed supports direct x 11 I think this may be the card to go with.

 

[Norlag]

Yes all 7000 series cards do.
