Also a friend told me that I should upgrade my GPU and I found this http://www.pcgarage.ro/placi-video/gainward/bliss-9500g...
but I'm not sure if it will fit well into my MB.
The reason why he recommended me to change the GPU is because of the bus which is 64 bit on the 8400 GS and the 9500GT is a 128 bit which he said its super ok...
Please consider both video cards (the one i have and the new one).
Additional information: I'm low on bucks(RON) and I presume that in USD it's somewhere near 64,59 $.
GT240 is kinda expensive... thus I know 9500Gt is not really an Gaming card... but does it perform better than 8400 GS? My friend showed me that he can run the game MW2 on 8400 GS but on low settings and 800x600 resolution only... and still he had some lag sometimes including slow motion effects. He said that the 9500GT is way more powerful. But it's up to what you people say If you know.
