R9 280x vs 290 in QHD, will it be a huge difference?
My previous system was
AMD Phenom II X4 980 Deneb O.C to 4.1GHz
PC3-12800 8G
GTX 550Ti 1G
1600*900 20" monitor
In a few months, I'll buy a QHD 27" monitor for around $280. I certainly doubt that 550Ti will work fine even after changing the monitor, so I'm planning to buy a new card.
I have 2 choices since my budget limit is around $300. I don't expect full or even high options, Medium option on 50~60 fps will be fine for me.
a. go for the R9 280x used for bitcoin and lightcoin mining. It will be around $200 for a used card. But somehow worried about the stability of card since it's been exhausted for almost half a year. can save some money.
b. I have a lot of 120mm fans in my case. So I think it will cover up the noise of the R9 290 Reference cooler. So buy used 290( not bitcoin miners) for around $280~310.
Would going to 290 with some extra money worth it? If there is no big difference, I will go to the 280x.
p.s would 600 watt power supply be fine for the system written above with 290 in it?
