* MSI GTX 980 Ti Gaming : Bought it in 2015. Gave it to a friend when I upgraded to 4k, because it can't make the cut at that resolution and I needed an urgent upgrade after moving to my Acer X27. Has 6GB and still very potent to this day at 1080p and 1440p. Was one of my greatest purchases ever. Lasting 4 years playing games at Very High and not being constrained by VRAM and not totally gimped at driver level (like the infamous 700 series) is a great achievement. Not only that, it also overclocked really well.
* EVGA GTX 470 1280MB : Bought it only for $225 at release. A 9000 folds step up from my 7600 GS and was the first card I owned to max out almost all the games at the time of its release, the image quality increase in games maxed out at 1080p (60fps+) when compared to low 800x600 (20fps+) was miraculous.
* Gigabyte HD 7950 WF3 : Sold the 670 and bought that card later, overall faster when overclocked and had 1 extra GB, an old OCNer
was a great marketer for these cards and he was the one to convince me to buy one of these.
* 2x Zotac RTX 2080 Ti AMP Ed : Great card that managed to allow me to play at 4k with max or near max settings. The crispness is incomparable with my Acer X27 when compared to my other monitors. But too bad it burnt a hole in my wallet.
* EVGA GTX 670 FTW 2048MB : Faster than the 470 by a good chunk. Was as fast as AMD's HD 7970, till AMD smoked it with their 12.11 WHQL drivers and HD 7970 GHz Edition release.
Garbage cards that I regret I wasted money on
* XFX FX 5500 256MB AGP : Was the first graphics card I bought from my savings, didn't play games well, unless set at 640x480 (1280x1024 was a high-end resolution back then) but I was a kid and it was all I can afford.
* PNY 7600 GS 512MB : Was a huge step up from the FX 5500 but still felt sluggish overall due to my Pentium 4 Prescott rig and its slow memory (533 MHz GDDR2 ram) but my budget was limited since I was a teen.
* EVGA GTX 780 Ti ACX : Had only 3GB VRAM, Watch Dogs was the first slap to the face to make this card a stutterfist with Ultra High textures, second slap was Shadow of Mordor, third slap was the neglected driver support from Nvidia when Maxwell released, leaving this card behind in the abyss, and the total ownage by AMD's R9-290X later in the game. Dropped $800 on the card, not happy at all. It also was a total dud overclocker that crash even with a meager +13 increase on the core. GTX 780 Ti was a nearsighted trash card, one of the worst I've ever owned.
* ASUS R9-290 4GB DCII : Hawaii was a great chip that lasted for a very long time, it is still good at playing games at 1080p with lowered settings. But that specific card was nothing short of garbage. Constantly reached 95c under load despite the beefy cooler, I researched more to find out the cooler was intended for GK110, that's why it didn't work very well at cooling the 290 (a way too late research).
