Hello everyone for a while now i was curious as to weather it would be good to upgrade me cpu to maybe something more up to date. i currently have a amd pehenom x4 945 and was considering getting a amd fx6300. gpu is a nvidia gtw 650 ti. also if i do upgrade where would i notice the differences
Hello,
You must do the upgrade only if your system is not doing its job anymore (ex. low FPS in games, high CPU usage in various scenarios, long completion task times). An FX-6300 will be an average upgrade from the x4-945 (5%-20% gains, depending on how well threaded are the applications), and that's only if your motherboard supports it (what motherboard do you have?).
The most worthy upgrade for your system would be a graphics card (GTX760, R9-270X), but only if you use an 1080p monitor and you are an avid gamer.
If you want a more responsive system, you could go for an SSD (an 128GB Samsung EVO is a good choice).
The best solution is to change the platform and go for an i5-4690 (over twice more powerful than x4 945), a Z97 motherboard and a GTX970 (and, of course, a new PSU, Seasonic S12II-520 for example).
