Hi guys,
I'm looking to upgrade my components and would appreciate some help as i'm years behind the hardware scene
What I have right now
Thermaltake Tsunami Dream case
Antec High Current Gamer 620W
ASUS A8N SLi-Delux motherboard
AMD Athlon 64 4400+ X2
nVidia GeForce 7800 GTX
Audigy X-Fi Fatal1ty
2gb Corsair RAM
...and a hard drive of some sort
The PC will be used for playing games such as Counter-Strike:Source, Counter-Strike:Global Offensive, F1 2011 and maybe Battlefield 3.
I have a budget of £300 to spend - Is this enough to upgrade and notice a big difference in performance?
I'm happy with my case, so i'd prefer not to replace that. I've also recently bought the Antec PSU, I take it this will be sufficient for a new build?
Final question
- Will I be able to use my sound card (its pretty old) in a new motherboard?
Thank you all verrrrrry much!
