Hi. I'm looking at upgrading my GPU. Currently I gave 2 GTS 450 in SLI. However I don't game a lot and would like to get one card that cuts the mustard. What I'm really after is a fairly quiet card for High definition video. I use MPC-HC with Madvr and I'm looking into really pushing the processing power of Madvr. GPU upgrades I'm considering could be new or second hand ; Gtx 960 / 970 Amd rx460 / 470 I'd welcome your thoughts or experience in this. By the way I'm using a 500w psu which I'm not upgrading right now. Thanks.
From my experience for a stable PC you must upgrade your 500w psu -> ~700w if you upgrade the GPU 500w is really limited and can lead to HD hadkrash (eg Peak load - when a usb is plugged in) spetial if the psu is old my best experience i got wit NVIDA GPU's edit: if you dont want upgrade your psu too - let it be never touch a running system
when I built my old unit I installed an 850w psu so I'm going to upgrade my gpu from a gtx 960 to a radon rx 480 strxrx480-o8g gaming gpu , I have an1200w psu sitting in the closet incase I need it . when ever you upgrade and you need a better psu always get the biggest you can afford that way you don't have to worry about having enough power for upgrades later on . come to think about it its time for me to get rid of all the 450w psu's I have in the closet ! I go to swap meets and buy computer parts for future use at a good price for me its a hobby.
Thanks for the replies. I'm well aware Of the power consumption issues and need for stable power supply. I've done my research and know that plenty of gpus run on a 500w psi. As I've said I'm not a big gamer, not will I be overclocking. What I'm interested in really is which card is going to perform well in a primarily htpc setup but at the same time pushing the settings of Madvr .
@alextheg well I'm suspect to tell but RX480 and PWU 1000W is fine for your desire; I think only testing to see only my 2 cents
I7 2600k on a Z68 G/byte G1 sniper2 rev1.0 mobo clocked to 4.6ghz. 16gb ddr3 ram, liquid cooled. I've done some reading over at Doom9 forums and what I can tell is that to push madvr settings like rendering / upscaling and image doubling one needs a fast somewhat higher end GPU. Question is deciding which to go for when budget is a constraint. Hence I'm considering second hand purchase.
That's another GPU I've been looking at , so much choice available right now it's just deciding between them I've got a Define R4 case so space is no issue.
If your budget allows, the 1080 card is the latest/greatest out there currently, and that only requires a 500w PSU The 9X cards are older and might be on sale
