When i buyed my PC i was able on running wot nearly all on MAX. But now i need to run it nearly all on LOWEST POSSIBLE.


So this is my configuration now:



Dual Core 2.91 GHz

HD 5450 1GB DDR3


Can i replace HD 5450 with HD 7750 1GB DDR5 and what kind of impovmant can i expect in FPS? And can my power supply support this graphic card? 400W?

Just because no one else has said anything I would consider upgrading the entire machine personally.


Your specs were good at one point, I know because I had a laptop running similar specs but for today's games I would consider upgrading everything.


I know its very easy for someone to say this but in all honesty you would be saving yourself money in the long run anyway,

OK, I'll bite :)


1. 2GB of RAM is kind of pushing it nowadays, even with WoT I think? Unless you're running Windows XP. It would be great if you could add even 1GB on top of that, 2GB would be best.

2. It would help if you listed the model name of your CPU (so I can see what generation it is). WoT is very CPU bound, 2,9GHz is kinda low unless your CPU is an Intel Haswell (4000 series) or Ivy Bridge (3000 series). It may be that this is your biggest bottleneck, if it's a Core 2 Duo for example or an AMD CPU.

3. HD5450 1GB upgrade to HD7750 is a huge step forward. The difference in performance is 5-8x depending on the application. However, IF your fps is bottlenecked by your CPU, it will mainly mean that your fps will stay the same, but you can use much better graphics settings (Improved Graphics, Post-Processing, View Range, way higher resolution, AA etc). The HD7750 is listed as a 55W GPU, so in a dual-core system a 400W PSU is more than enough.
