Emachines... Upgrade Parts Help

[NicholasECharles]

So i got a Emachines E1331G... Ive read about how this pc was good as in being able to upgrade it's parts. Now i know not much a lot about parts and upgrading a pc. I need help with upgrading its Video card and other stuff to be able to play games like BattleField 3 on high settings if that's possible. Right now i can barely play Left 4 Dead 2, Half-Life 2 Team Death match 2. Its lags a little.

Spec's Now:

Operating System:

Windows 7 Home Premium 64-bit (6.1, Build 7601) Service Pack 1

System Manufacturer: eMachines

System Model: ET1331G

BIOS: Default System BIOS

Processor: AMD Athlon(tm) II X2 235e Processor (2 CPUs), ~2.7GHz

Memory: 6144MB RAM

Chip type: GeForce 6150SE nForce 430


Question 1 : What do i need to replace ?
Question 2 : What should i get ?
Question 3 : Do I have space in my pc for the parts ?

Thank You.

A1. That would really depend on what resolution you game on

A2. If sticking to current platform, depends on what CPU mobo supports? I suspect a 95W TDP limit so i'd hunt used/on the cheap 95W Deneb X4, a HD 7850 and possibly a PSU upgrade and ease off settings/resolution if need arises

A3. Check GPU length limitation of case and you need better fans in these OEM casings as they were designed for home/office use not gaming rigs

Ya prolly a PSU upgrade and if u find your games a tad more CPU intensive i'd look at something like a Athlon II X3/X4 and call it a day ^^
