Thanks a lot for the anwser. Im not much of a tech guy and had no clue the card was that bad. I'll be looking for a new one.
A couple of tips: There are many sites doing benchmarks and recommending graphics cards in various price brackets. Do read up a bit on the current crop of cards before you buy. Look at relevant benchmarks; i.e. you probably don't care about which card performs best at 4k if you don't use a 4k screen.
You will want to figure out how much juice your power supply puts out (Amps at 12 V, total wattage, are there spare PCI-E connectors?); it usually says in plain text on the side. You don't want to put in a new 750 W power supply and a massive 300 W card in a tiny, poorly ventilated computer case; odds are if you didn't build it yourself, the powersupply that's already in there is appropriate for the chassis. (cards can indeed be larger than what will fit inside a midi case!).
Don't rely on "series number" as an indicator of performance; it's not, it just indicates when the card was released. A newer card may just be a rebadged of the same chip with minor tweaks; a card from an older series can be faster. E.g. an nvidia 780 ti is an older high end card and is faster than a 950, which is a newer mid-end card. Often there are good deals when an older generation is phased out. Again, look at benchmarks, look at how much power it can draw.
The total amount of graphics card RAM does matter, but it's not hugely imporant. A low end card can have a lot of ram because it's cheap, slow RAM. Again, look at the benchmarks.
A properly designed cooler may be worth a little bit extra compared to a cheap "leaf-blower" design. Stock fans are much better than they used to be back in the day(e.g. see FX 5800 ultra, for something right out of the little shop of horrors). You can usually get a much better fan design for $10 euro extra. You want a big chunk of aluminium with heat pipes and large, slow moving fans; several of them on a high end card. Large, slow fans just give you a low mellow sound of flowing air; it's not annoying; a single tiny radial fan spinning at 8000 RPM may cool just as well, but it will sound like a hair dryer with a loud, annoying high-pitched whirr. Lower end cards need much less cooling so compare same for same (e.g. if decide you want a R9 370, compared different makes of the same card; a R9 390 will of course have a much better fan and it will need it).
