Derp that Google Drive image is private; use something like imgur: the simple image sharer
Q - What are your system specs??
There's a huge difference between 'running' something i.e. a game and playing it where you'll have enjoyment playing it, not to mention in Multiplayer being remotely 'competitive.' In most situations I recommend a GPU's like GTX 660 or HD 7870 or higher. Even for the Campaign you'll want a minimum of 45+ FPS.
sorry for the image, here an other link, should work: https://drive.google.com/file/d/0B7isitVP3Z7HamhEbDVNY2djM00/edit?usp=sharing
As for my pc specs,
my cpu is a core i3 2100(I will upgrade that too in a few months)
For the gpu, see the image
RAM: 8 GB
HDD: 1,5 TB
Hmm...doubtful the GTS 450 is significantly faster than the GT 430 - http://www.hwcompare.com/7606/geforce-gt-430-vs-geforce-gts-450/
Nvidia is having a price war right now with AMD, and you'll need a new GPU to run Ghosts. Also, Black Friday and Cyber Monday are going to be here soon enough. Clearly you can attempt to OC your GPU to its gills (try MSI Afterburner) and see what happens. However, in Multiplayer you'll have a really tough time even if it loads and runs.
Additionally, sometime between Nov 5th and 6th there will be a lot of official benchmarks, see a GPU where you can sustain 60 FPS or higher.
No do not buy a gts450 that really old tech and at 110euros?
Get a better card like the 7850, at the minimum get yourself a newer card like a radeon 7790 or a 650ti boost edition.. both should be around that 110euro mark.
Make sure your pc has a large enough power supply.
I know the 7790 is about $100 usd and the 650ti Boost is about $130 usd.. You can overclock the 7790 and hit the 650ti Boosts speeds, probably the best bang for the buck in the price range.. otherwise wait to see more blackfriday deals, I use slickdeals personally or overclock nets online deals.
