Upgrade from 4670

[akxpckwb]

Hey guys
Currently I'm using a hd4670 1GB GDDR3 however I got a little money to spare and these are my options(only options really):
->HD6670 (either 1BG ddr3 or 1GB gddr5)
->GT440 (either 1gb gddr5 or 2gb gddr3)
->GT520 1GB DDR3
->HD6570 1GB DDR3
->HD7750 1GB GDDR5
->HD6750 1GB DDR5
->GTS450 1GB DDR3(or ddr5)
->HD6770 1GB GDDR5

I'm using a G620 with 4GB RAM and a P8H61M. Monitor resolution is 1360x768. It's mostly for gaming albeit not heavy stuff ( don't like crysis or bf3 )
I know these are a lot of options with different costs but it's all I can get my hands on.

Thanks in advance for all replies

i would go for the 7750, same performance as 6770 and uses less power.

How much less? If the performance is indeed the same the 6770 is around 30€ cheaper. I do have a weak PSU but it can handle any of them...hoppefully

what brand is your psu? the 6770 needs a power connector while the 7750 does not.

I'm thinking about getting a Grimtec 500watts PSU. You probably haven't heard of them tho since I live in the middle of nowhere

DO NOT get that power supply. It's bad and it could blow up your computer at any time. Only get power supplies from reputable brands, because that's THE computer component which could kill the whole computer. The reputable brands include: Corsair, Antec, Seasonic, Rosewell, Fortron Source (FSP), OCZ and XFX. The hd6770 requires at least 400W quality power supply. HD7750 could get away with generic 400W power supply, I guess.

Yes I know about the reputable brands and the dangers of low-end PSU's but I've been running a low-end PSU for almost a decade now and it's all good. It will probably blow my whole system when it fails but it's lasting long and it was very cheap.

Anyway PSU's apart the 7750 is the best among that list?

I'd go with http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026 because ATM after mail-in rebates it costs only $24.99

Newegg doesn't ship to where I live and I'd rather get a new GPU than a quality PSU.
I might get a good PSU in a few months but can't afford it at the moment
