Hello. My curretn PC was built about 5 years ago, so I intend to upgrade it.
I'm on budget, so I'm only planning to add some Ram and get a new graphics card.


I'm planning to get a GTX 780 or 760.However, I have concern about if my current motherboard (Asus P7P55DE- Deluxe) is compatible... The reason is that as I was checking the specs of the MB, I noticed it says PCI Express 2.0 but the cards stated above use 3.0 I believe.

Does this mean I'll have to include a motherboard (and CPU) in this upgrade inevitably?

Thanks.

No that card would work, it just goes a small prob unnoticeable amount slower. Down the road you can always upgrade the board and chip but for now that card would fit. just make sure you have enough room in the case, they are longer than you'd expect.

PCI-e standards are all backwards compatible, it's just that the card will be limited to the speed of the motherboard slot. Right now, there is little to no performance difference between PCI-e 2.0 to 3.0 at 8x and 16x. You should have no problems running even a 960 or 980.

It will work, might require a bios update. (I'v run into that before on an MSI board)
May I ask your graphics card budget?
What PSU do you have, the 760/780 require more power than newer maxwell based cards.
The Gtx 780 and 760 are older cards, unless your getting a deal on them you probably want a new architecture.

Yes,I've been considering the 970 as well... The thing is, as I've stated above, I'm not the type that touches the rig before 3-4 years once renewed, unless something absolutely revolutionary happens... (Dx 10 was one case) So it's likely that I will upgrade the CPU and the MB sometime once they reach their limit too, but then I'll probably be keeping the GPU...

What concerns me with 970 was the infamous Vram incident. I understand that today's games in 1080p don't demand the vram to use the last 500mbs, but will it still be the case after 3 to 4 years? Will a newer GPU chipset or a fully intact vram have more advantage after all that time? That's the point I couldn't decide...

Future proofing doesn't work, all you can do is get what is the best value for your money now. Even with the ram issue the gtx 970 is a good value. (This coming from a huge amd fan).
Considering most cards are 4GB max, unless you specifically spend more for an 8gb version (like the r9 290x 8gb version)
It's pretty safe to get a gtx 970.

Developers aren't going to start hitting more than 3.5gb minimum vram for a LONG time, because no one would be able to buy and play their games.
Spending more now for vram you may or may not use in the future is not a good investment, save that money and if it becomes an issue upgrade later.
