My last few GPU's
GTX 970. Good GPU and great value
GTX 1070. also a great GPU, i liked it a lot, quite a hike in price from the 970 tho, from a value perspective it was still quite good, it was very much stronger than the 970 and had 8GB of VRam.
RTX 2070 Super, another chunky hike in price but again also a solid chunk higher performance, still ok from a value perspective, as for RT its one up from useless on this card.
--------
RTX 3070, didn't buy it. Same price as the 2070 Super but the raster performance is also not a great deal better, its minimal from what you would expect, around 25% gen to gen, this is when Nvidia started pushing RT as the thing you're supposed to be paying for, not interested, its far too early for RT to replace raster performance.
