I'm not.
I'm selling at this price because of the brand. If this is some random Palit / Leadtek / Weird unknown brands, i would have priced it below $200.
Please also note the GTX770 has about 90% the performance of a GTX1050Ti based on benchmarks. A new Asus GTX1050Ti price is as follows
1) Strix 1050Ti = $329
2) Expedition 1050Ti = $289
3) DUAL 1050Ti = $269
Of course, the 1050Ti has 4GB memory while my 770 only has 2GB. That's the catch. And yes I did mention prices are negotiable. Because I'm sick of encountering low ballers.
The GTX 770 has the same core as a GTX 680, albeit with a higher clock.
A GTX 690 has two GTX 680 cores and 2 X 2 GB VRAM, essentially GTX 680 SLI in one card. That was sold recently for $240, which is only slightly higher than the $230 you are asking for. The GTX 690 came with a free brand new mini-DP cable ($25 cost).
I grant you that the Asus GTX 770 has a very good cooler. The GTX 690 came with an Arctic Accelero 690 custom cooler which is much better. The stock 690 cooler has vapor chamber tech which is already better than the Asus DirectCU cooler and the Arctic Accelero 690 beat the stock cooler by around 10 to 15C.
No matter how you look at it, the Asus GTX 770 is overpriced at $230.
You can sell the Asus GTX 770 for whatever price you like. However, if you try to convince a noob that it is a good buy, you can expect fellow HWZers to respond.
