小弟最近 GTX7...(恕刪)
小弟我最近也要入手GTX-770
也在為2G還是4G煩惱得不可開交
畢竟以EVGA為例 價錢太高了 還是要將近15K
所以GOOGLE到國外去了
得到了結論
------------------------------
Conclusion
This has been quite an enjoyable exploration for us in comparing the 4GB vRAM-equipped EVGA GTX 770 SC to the 2GB reference GTX 770 at the same clocks. Unless a gamer plays at 5760×1080, we wouldn’t recommend choosing 4GB vRAM over 2GB for a single GTX 770 for today’s games. However, if a gamer is planning to SLI GTX 770s at 5760×1080, then it might be reasonable to pick the 4GB version. We can’t predict future performance of upcoming games so we will leave them out of our equation.
Pros – 4GB over 2GB
The EVGA GTX 770 4GB SC provides excellent performance for a 4GB $459 card even when clocked to the reference card’s clocks and it provides marginal improvements at super-widescreen resolutions.
SLIing two or more 4GB cards has more room for better performance at 5760×1080 over SLI’ing 2GB cards.
Cons
Cost. 4GB-equipped GTX 770s cost about $40 to $50 more than their 2GB counterparts.
4GB is generally unnecessary for 1920×1080 or even for 2560×1600. Only marginal benefits are found at 5760×1080 for a single card.
The Verdict:
We would not recommend buying a single GTX 770 4GB card over the 2GB version if there is a significant price difference. We might recommend choosing 4GB GTX 770 SLI over 2GB GTX 770 SLI, but only if the gamer plays at super-widescreen resolutions or requires extreme anti-aliasing.
Stay tuned, there is a lot coming from us at ABT. Next week, expect an evaluation of Cooler Master’s Comforter Air laptop cooler. We also received a Hall of Fame GTX 770 from Galaxy and there will be a showdown with the EVGA GTX 770 SC as well as a comparison with the reference GTX 770, also scheduled for next week. And it will lead to a GTX 770 SLI evaluation the week after.

實際測試的網站
給有一樣煩惱的玩家做參考吧
雖然裡面沒有測試BF4跟COH2
不過有很多遊戲都有開到5760*1080
EVGA ACX-SOC GTX770 2GB都能挺過難關
EVGA ACX SOC-2GB VS 4GB
測試完畢之後 以770來說 要是突破VRAM 2GB大關 大概770也附載不了了 除非有打算做SLI的
