thanks I didn't about modifying a monitor
It's not difficult. Just a bit of research.
T-Con swap-outs became the "in thing" when 120Hz arrived on the scene alongside cheap Korean IPS 2560x1440 monitors.
Overlord became somewhat synonymous with retrofitting of Yamakazi Catleap's, Shimian's (which I use), and a host of other Korean panels. This will give you an idea of how easy the operation is
there is also brand loyalty in the matter.. I have seen many people say they want a nvidia gpu even if amd will save them money or let them get a stronger gpu.
what I never liked about nvidia gpu's is the 770's having 2gb of vram.. kinda weak if you want to sli and that extra gig of vram in a 280x-79xx has always been better for running mods and crossfire so I could never understand the brand loyalty if your budget falls into that bracket.
Some people do have an unwavering allegiance, but as a general rule you should buy the best you can for the money you're spending. I tend to buy Nvidia, and more often than not EVGA cards, simply because I upgrade often and these hold their value in the resell market. EVGA's warranty is serial based, so the card can pass through many owners but the warranty is tied to the board not the original owner and documentation. Transferable warranties add value to the sale even if it is largely illusionary since cards don't usually fail within the warranty timeframe, and any warranty claim means sending the card halfway around the world ( shipping cost).
Having said that, I wouldn't get hung up too much on the GTX 770 or the 280X - they are firmly in the budget conscious realm of a previous generation of architecture. If you were considering a 1920x1080 maybe, but it isn't a good match (performance or price) for an expensive 2560x1440 panel. As for vendor specificity, anyone running current Nvidia hardware only has G-Sync as an option, but I wouldn't bet against the next round of releases (from both AMD and Nvidia) having DP 1.3 support now that the spec is finalized. It would seem rather short-sighted not to include it.
