You should read about Direct X 11.2 wink.gif

With DX 11.2, VRAM worries may be a thing of the past.

EDIT 1: As it stands, my prediction is that the GTX 700 series+ and HD 7000 series+ will be supported. XB1 will use DX11.2, and the XB1 has an APU with an HD 7870, so HD 7000 series support just seems logical.

Most games do fine with 4GB main memory, and all of a sudden less than 4GB @ VRam is obsolete?
2GB will suffice for a loooooong time, should you stop just "maxing out" everything.

You know, those 12 GByte/sec or so one-way bandwidth of 16x PCIe 3.0 Lanes, are no joke - the GPU can exchage a whole lot of information with the system's RAM pretty fast. rolleyes.gif

I much rather have 2 extra GB of video memory running @7GHz+ which is proven to works flawlessly, than rely on slower system memory, and having to upgrade to windows 8.1. I remember how big the fire works were for readyboost, and how not having enough system ram was the "thing of the past" wink.gif

Considering they have the GPU power of an entry to mid level gaming PC though, I doubt they'll be pushing the graphics boundaries so much as they'll be alleviating the ball and chain that consoles have been for PC games the past several years. Even if they used all 8GB for graphics, it would be like having a GTX 650 8GB, which would be just silly.

im asking about the 4gb gpu because i plan on going sli with two 770's and didnt know if i should purchase two 4gb or 2 2gb cards.

If you plan on keeping the cards for 4 years, then you will need 4GB for cross platform games on high settings.

Next gen consoles have 7/8 GB shared RAM, and devs will be filling that up extremely quickly. They'll switch to more RAM intensive algorithms, etc. Also, since next gen consoles have unified RAM, any data that game devs use on both the CPU and GPU (which will be more than you think, because the CPUs are weak on PS4/XB1 and the GPUs can do a fairly wide range of computation) will need to be mirrored in both system RAM and VRAM for PC customers. Lastly, Windows APIs are more abstracted and less RAM efficient than the console counterparts. Even strict console -> PC ports aren't anywhere near the 512mb (system+VRAM) limit of the 360/ps3, so expect a game using 8GB on next gen consoles to use far more with equivalent data sets.

tl;dr - future console ports will be very very RAM hungry.

I suggest the 4GB since IMO 2560 x 1440p name brand monitors will be around $250 bucks in the next 1 1/2 years and you will probably be getting one or maybe even two. Not to mention as folks are claiming the newer games will be more memory intense. That extra 120 bucks for the 4GB cards now might save you some money in the long run.

iirc the OS uses 1.5 gigs and the game(s) use 2.5+gigs. that allows the games to be able to allocate ~4 gigs of ram but not necessarily use it. if also considering we are talking a 7850/7870 i highly doubt it.

i think the potential problem isn't the amount but the bandwidth with consoles having ddr5 with 170/Gbs(?); 192 bit busses may choke.
